5. Click Advanced and select the DNS tab. If there are any DNS server IP addresses listed there, write them down for future reference, and remove them from this window.
6. Click OK.
7. Select Use the following DNS server addresses. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference.
8. Replace those addresses with the IP addresses of the Google DNS servers: 8.8.8.8 and 8.8.4.4.
9. Restart the connection you selected in step 3.

Mac OS X

DNS settings are specified in the Network window.

Example: Changing DNS server settings on Mac OS 10.5

* To change the settings for an Ethernet connection, select Built-In Ethernet, and click Advanced.
* To change the settings for a wireless connection, select Airport, and click Advanced.
4. Select the DNS tab.
5. Click + to replace any listed addresses with, or add, the Google IP addresses at the top of the list: 8.8.8.8 and 8.8.4.4.
6. Click Apply and OK.

Linux

In most modern Linux distributions, DNS settings are configured through Network Manager.

Example: Changing DNS server settings on Ubuntu

1. In the System menu, click Preferences, then click Network Connections.
2. Select the connection for which you want to configure Google Public DNS. For example:

Enhance your internet activities with Sea Monkey

Folks today i gonna tell you about a very interesting internet suite named "SeaMonkey". It is considered as the modern internet suite. Such a software suite was previously made popular by Netscape and Mozilla, and now the SeaMonkey project continues to develop and deliver high-quality updates to this concept.

SeaMonkey has inherited the successful all-in-one concept of the original Netscape Communicator and continues that product line based on the modern, cross-platform architecture provided by the Mozilla project.

1>The Internet browser at the core of the SeaMonkey suite uses the same rendering engine and application platform as its sibling Mozilla Firefox, with popular features like tabbed browsing, feed detection, popup blocking, smart location bar, find as you type and a lot of other functionality for a smooth web experience.
2>SeaMonkey's Mail and Newsgroups client shares lots of code with Mozilla Thunderbird and features adaptive Junk mail filtering, tags and mail views, web feeds reading, tabbed messaging, multiple accounts, S/MIME, address books with LDAP support and is ready for both private and corporate use.
3>Additional components include an easy-to-use HTML Editor, the ChatZilla IRC chat application and web development tools like a DOM Inspector and a JavaScript debugger.
4>If that's still not enough, SeaMonkey can be extended with numerous Add-Ons that provide additional functionality and customization for a complete Internet experience.

Display a message box before User Logon

If you want to pop up a message box when Computer starts and before logon screen on Win9X or WinNT, then you can use this trick.

Run the Registry Editor using Start->Run and then type "regedit" and Enter. You will come up with a windows with title Registry Editor. You will see that something like this.

Here is a view of Registry editor. On the left pane we have a tree view with some items. These are actually the roots of different types of keys. We are going to to discuss only two of them which are needed by us. The remaining will wait for another time.

HKEY_CURRENT_USER holds the information about the currently logged on user.

HKEY_LOCAL_MACHINE holds the information about the whole computer.

Go to:

For Win9X
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\WinLogOn

And For WinNT
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\WinLogOn

And make two String Keys named

LegalNoticeCaption and LegalNoticeText

Put any value which you want to display. First is the Title of the Message box and second is the text to be displayed. After doing this, you will get welcome message each time windows starts.
NOTE: Modifying the registry is dangerous. If you make any mistake you may corrupt your registry. This may cause your system to crash or become unstable.

For IT Engineers appreciation

An IT Engineer unpacked the server from its box, installed an operating system, patched it for security, made sure the power and air conditioning was working in the server room, monitored it for stability, set up the software, and kept backups in case anything went wrong.

An IT Engineer installed the routers, laid the cables, configured the networks, set up the firewalls, and watched and guided the traffic for each hop of the network that runs over copper, fiber optic glass, and even the air itself to bring the Internet to your computer. All to make sure the webpage found its way from the server to your computer.

An IT Engineer makes sure your network connection is safe, secure, open, and working. A IT Engineer makes sure your computer is working in a healthy way on a healthy network. A IT Engineer takes backups to guard against disaster both human and otherwise, holds the gates against security threats and crackers, and keeps the printers going no matter how many copies of the tax code someone from Accounting prints out.


An IT Engineer worries about spam, viruses, spyware, but also power outages, fires and floods. When the email server goes down at 2 AM on a Sunday, your IT Engineer is called, wakes up, and goes to work.

An IT Engineer is a professional, who plans, worries, hacks, fixes, pushes, advocates, protects and creates good computer networks, to get you your data, to help you do work -- to bring the potential of computing ever closer to reality.

So if you can read this, thank your IT Engineer -- and know he or she is only one of dozens or possibly hundreds whose work brings you the email from your aunt on the West Coast, the instant message from your son at college, the free phone call from the friend in Australia, and this webpage.

Show your appreciation

Friday, July 31, 2009, is the 10th annual IT Engineer Appreciation Day. On this special international day, give your IT Engineer something that shows that you truly appreciate their hard work and dedication. (All day Friday, 24 hours, your local timezone).

Let's face it, IT Engineers get no respect 364 days a year. This is the day that all fellow IT Engineers across the globe, will be showered with expensive sports cars and large piles of cash in appreciation of their diligent work. But seriously, we are asking for a nice token gift and some public acknowledgement. It's the least you could do.

Consider all the daunting tasks and long hours (weekends too.) Let's be honest, sometimes you don't know your IT Engineers as well as they know you. Remember this is one day to recognize your IT Engineer for their workplace contributions and to promote professional excellence. Thank them for all the things they do for you and your business.

And Donot even dare to forget Me in this appreciation.

When your ISP's DNS is down

This for all my Pakistani friends who are using PTCL DSL. Usually People who are using PTCL complains that there DSL link is sync but still they are facing problem in browsing a web site. What they have to do is just first ping their gateway then the DNS. If gateway is pinging but the DNS is not use the following solution.

Before we start firstly we have to understand the work of DNS. When you type an address like www.yahoo.com in your browser address bar, the computer doesn’t know where yahoo.com points and it will therefore ask the DNS server.

The job of a DNS server is to translate this human-readable web address (like www.yahoo.com) into a computer-readable number also known as an IP address (209.131.36.158). Once your computer knows the IP location of a web domain name, it opens the website in your browser.

DNS is such an integral part of our Internet life working behind the scenes every time we connect to a website. In most situations, our Internet Service Provider specifies the DNS Server address that we key into the browser network settings or the router.

Now back to our problem. To solve this problem, we look at a simple and reliable service called OpenDNS that speeds up your Internet connection and also handles some other very important issues. There are no software to install, it’s very easy to set up and the price is just right - $0.

To use OpenDNS, all you have to do is open your Network Connections or Router’s settings page and update the default DNS server to point to the OpenDNS nameservers that are 208.67.222.222 and 208.67.220.220.

Unlike the DNS servers of your less reliable ISP, OpenDNS servers store the IP addresses of millions of websites in their cache so it would take less time to resolve your requests. So if you have asked for an IP address of a website that has been previously requested by another OpenDNS user, you will get the reply instantly.

Another huge advantage of using OpenDNS is that it blocks phishing websites from loading on your computer. It uses data from Phishtank, a community site that is also used by Yahoo! Mail to determine if some particular website is part of any online phishing scam.

OpenDNS also takes care of any typos that you commit while typing the name of popular websites. For instance, if you type www.gogle.com omitting the additional “o” by mistake, OpenDNS will open the main www.google.com site automatically.

If you are a parent worried about kids visiting adult websites on the home computer, you can configure OpenDNS to block any adult website from loading on the computer. In fact, quite a few business places use OpenDNS to block social sites like MySpace and Facebook on employee computers.

Power users can assign abbreviations or OpenDNS Shortcuts to access their favourite websites more quickly.

For instance, you can set “mail” as a shortcut for http://mail.google.com/ or something like “a” for www.reallylongname.com - just type the shortcut to access the site. A good alternative for browser based bookmarks and it works across all computers where you have logged in to your OpenDNS account.

So enjoy...........

How to change Windows XP's administrator Password

Dear readers, I am here with an amazing trick. Most of my friends ask me that how can they change their Windows XP forgotten password. So here is the solution.

1. Place your Windows XP CD in your cd-rom and start your computer (it’s assumed here that your XP CD is bootable – as it should be - and that you have your bios set to boot from CD)

2. Keep your eye on the screen messages for booting to your cd Typically, it will be “Press any key to boot from cd”

3. Once you get in, the first screen will indicate that Setup is inspecting your system and loading files.

4. When you get to the Welcome to Setup screen, press ENTER to Setup Windows now

5. The Licensing Agreement comes next - Press F8 to accept it.

6. The next screen is the Setup screen which gives you the option to do a Repair.

It should read something like “If one of the following Windows XP installations is damaged, Setup can try to repair it”

Use the up and down arrow keys to select your XP installation (if you only have one, it should already be selected) and press R to begin the Repair process.

7. Let the Repair run. Setup will now check your disks and then start copying files which can take several minutes.

8. Shortly after the Copying Files stage, you will be required to reboot. (this will happen automatically – you will see a progress bar stating “Your computer will reboot in 15 seconds”

9. During the reboot, do not make the mistake of “pressing any key” to boot from the CD again! Setup will resume automatically with the standard billboard screens and you will notice Installing Windows is highlighted.

10. Keep your eye on the lower left hand side of the screen and when you see the Installing Devices progress bar, press SHIFT + F10. This is the security hole! A command console will now open up giving you the potential for wide access to your system.

11. At the prompt, type NUSRMGR.CPL and press Enter. Voila! You have just gained graphical access to your User Accounts in the Control Panel.

12. Now simply pick the account you need to change and remove or change your password as you prefer. If you want to log on without having to enter your new password, you can type control userpasswords2 at the prompt and choose to log on without being asked for password. After you’ve made your changes close the windows, exit the command box and continue on with the Repair (have your Product key handy).

13. Once the Repair is done, you will be able to log on with your new password (or without a password if you chose not to use one or if you chose not to be asked for a password). Your programs and personalized settings should remain intact.

I tested the above on Windows XP Pro with and without SP1/2/3 and also used this method in a real situation where someone could not remember their password and it worked like a charm to fix the problem. This security hole allows access to more than just user accounts. You can also access the Registry and Policy Editor, for example. And its gui access with mouse control. Of course, a Product Key will be needed to continue with the Repair after making the changes, but for anyone intent on gaining access to your system, this would be no problem.

And in case you are wondering, NO, you cannot cancel install after making the changes and expect to logon with your new password.

Cancelling will just result in Setup resuming at bootup and your changes will be lost.

Ok, now that your logon problem is fixed, you should make a point to prevent it from ever happening again by creating a Password Reset Disk. This is a floppy disk you can use in the event you ever forget your log on password. It allows you to set a new password.

Here's how to create one if your computer is NOT on a domain:

Go to the Control Panel and open up User Accounts.
Choose your account (under Pick An Account to Change) and under Related Tasks, click "Prevent a forgotten password".
This will initiate a wizard.
Click Next and then insert a blank formatted floppy disk into your A: drive.
Click Next and enter your logon password in the password box.
Click Next to begin the creation of your Password disk.
Once completed, label and save the disk to a safe place
How to Log on to your PC Using Your Password Reset Disk

Start your computer and at the logon screen, click your user name and leave the password box blank or just type in anything. This will bring up a Logon Failure box and you will then see the option to use your Password Reset disk to create a new password. Click it which will initiate the Password Reset wizard. Insert your password reset disk into your floppy drive and follow the wizard which will let you choose a new password to use for your account.

Now Recover your files with ZAR

Folks, it some times put you in hell when a disaster strikes to your computer. Data can be lost due to many different reasons. Accidental reformatting, power spikes, virus attacks and hardware malfunction are some of the scenarios where you will find yourself looking for a data recovery solution.

But now we don't need to worry about it alot, Zero Assumption Recovery provides a suite of highly effective and thorough data recovery software for Microsoft® Windows™ operating systems. ZAR is suitable for home users and small businesses who need a powerful data recovery solution for FAT16/FAT32/NTFS file systems. The default settings are reliable and thorough, but more technical users can benefit from a wealth of optional configurations.

Features

The main features of our Windows data recovery software are:

Runs on Windows NT/2000/XP/2003/Vista
Supported filesystems are FAT16, FAT32 and NTFS (all versions)
Provides limited ext2 (Linux filesystem) support
Support for partition recovery
Support for hardware RAID0 and RAID5 recovery
Long and national file names are supported
Native NTFS compression is supported

What makes ZAR different?

There are three main reasons:

Firstly, it is easy to use. You can recover the data yourself as long as you are reasonably familiar with computers. ZAR is ideal for the home user who knows what a hard drive is and how many there are in his system - but more technically minded users can also benefit from a wide range of configuration options.

Secondly, it takes its time. When you are trying to recover critical data, you need to be persistent and painstakingly thorough. ZAR slowly and methodically crawls through your disk, checking and cross-checking everything and recovering as much data as possible. Faster programs may skip though your disk in seconds and come out empty-handed. ZAR persists, and succeeds.

Thirdly, it is more powerful than most. We know that you are trying to recover important data, and that every single piece that you retrieve could be vital. With Zero Assumption Recovery, nothing is assumed - ZAR never relies on anything located on the damaged disk. If incoherencies are discovered, thorough checks and cross-checks are used to derive the necessary information. The algorithms are built to withstand a severe pounding, which means that ZAR can recover data even when things seem hopeless.

ZAR 8.4 system requirements and demo version restrictions

Windows 2000/XP/2003/Vista.
Additional media to recover data to (never save files to the volume you are recovering, for this may cause further damage to the volume!)
Damaged drive must be physically functional. It should be at least detected by BIOS. Multiple bad sectors can be handled (but the data they contained is lost forever), but controller failures are beyond any software repair.
Supported filesystems:

FAT16 (Used in Windows 95) and FAT32 (used in Windows 95 OSR2, 98, ME, 2000 and XP)
NTFS versions 1.2 (Windows NT 4.0), 3.0 (Windows 2000), and 3.1 (Windows XP/2003/Vista).
Limited ext2 (Linux filesystem) support
Digital image recovery function operates regardless of the filesystem type.
Supported RAID layouts:

Hardware RAID0 and RAID5 with any number of member disks.
It is possible to recover Windows 2000 Server, Windows 2003 server software RAID0 and RAID5 if the RAID members occupy the entire physical disk.
There are the following limitations in the evaluation version of ZAR 8.4:

Only (up to) four directories can be recovered in the demo version of our computer data recovery software.
The demo version is unable to load the scan result file. However, it does save these files to avoid having to rescan the disk when you got the full version.
In digital image recovery mode program operates as freeware with no functional limitations. List of known compatible digital camera models and image formats is available Known camera compatibility list here.

Zmeil 2.1 system requirements and demo version restrictions

Windows NT, 2000, XP, 2003 or Vista.
Internet Explorer 5.0 or later.
Plenty of a free disk space to store the recovered files. It is recommended to have a at least twice the size of the damaged email database available.
The evaluation version of Zmeil 2.1 only recovers 9 messages maximum per the database.

Zlon 1.0 system requirements and demo version restrictions

Windows NT, 2000, XP, or 2003.
The evaluation version of Zlon 1.0 expires in 14 days. If you want to use it past the expiration you will need to order the unlock code from us.

Zero Assumption Disk Space Visualizer 1.2 system requirements

Zero Assumption Disk Space Visualizer 1.2 runs generally on any machine Windows runs on, with the exception of the original (pre-OSR2) Windows 95 release and Windows NT 3.51.

BIOS Beep Codes

Friends It some times put you into hell when you have to do an important assignment and just at that moment your system does not start and start giving beeps. There are two ways to troubleshoot whether you do it by yourself or wait for the technical support from any hardware shop.
As you are the reader of this blog so i do not make you depend on any one. Now after reading this post you will be able to understand the beep codes and you can easily troubleshoot your system with out the help of any technical freak.

Let's Start

When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected.
Because there are many brands of BIOS, there are no standard beep codes for every BIOS.

The two most-used brands are AMI (American Megatrends International) and Phoenix.

Below are listed the beep codes for AMI systems, and here are the beep codes for Phoenix systems.

AMI Beep Codes

Beep Code Meaning
1 beep DRAM refresh failure. There is a problem in the system memory or the motherboard.
2 beeps Memory parity error. The parity circuit is not working properly.
3 beeps Base 64K RAM failure. There is a problem with the first 64K of system memory.
4 beeps System timer not operational. There is problem with the timer(s) that control functions on the motherboard.
5 beeps Processor failure. The system CPU has failed.
6 beeps Gate A20/keyboard controller failure. The keyboard IC controller has failed, preventing gate A20 from switching the processor to protect mode.
7 beeps Virtual mode exception error.
8 beeps Video memory error. The BIOS cannot write to the frame buffer memory on the video card.
9 beeps ROM checksum error. The BIOS ROM chip on the motherboard is likely faulty.
10 beeps CMOS checksum error. Something on the motherboard is causing an error when trying to interact with the CMOS.
11 beeps Bad cache memory. An error in the level 2 cache memory.
1 long beep, 2 short Failure in the video system.
1 long beep, 3 short A failure has been detected in memory above 64K.
1 long beep, 8 short Display test failure.
Continuous beeping A problem with the memory or video.
BIOS Beep Codes

Phoenix Beep Codes

Phoenix uses sequences of beeps to indicate problems. The "-" between each number below indicates a pause between each beep sequence. For example, 1-2-3 indicates one beep, followed by a pause and two beeps, followed by a pause and three beeps. Phoenix version before 4.x use 3-beep codes, while Phoenix versions starting with 4.x use 4-beep codes. Click here for AMI BIOS beep codes.

Change your Folder Color

iColorFolder enables you to easily customize the color of each WindowsXP folder icons, using one of the standard color choices, or a custom folder skin (Aqua, Mac OS X, Vista and others). iColorFolder is a very light soft, that doesn't stay in memory. It uses a native functionnality of WindowsXP to be more efficient. Discover it's simplicity: with a single right-click on a folder you colorize it ; the necessary and only the necessary. iColorFolder is proudly an Open-Source program. Like the folder icons, iColorFolder makes folder navigation in Windows easier, in this case by letting you assign colors to your folder icons, which is done from the right-click context menu. It also lets you assign custom icons and comes with three different icon skins, but it also works fine if you're already using some icon customization/skin tool. Even better, iColorFolder is open source software and takes up little memory.

How to stop illegal usage of your WIFI

Friends after a long time spending on stressful projects, I am here to tell you some thing really important. As I have discussed in some of my older posts about Wireless hacking and tools which can stop it. Now I am here with an amazing new tool.This tool called Moocher Hunter can help you physically track the users connected in your WiFi network. This tool would come handy for network admins and any personnel who wants to stop unauthenticated use of his wireless router.

1. Its free to use.
2. It can predict the physical location of the computer using the WiFi connection.


The algorithms applied use various signal variables to accurately predict the position of the connected laptop/machine. MoocherHunter™ identifies the location of an 802.11-based wireless moocher or hacker by the traffic they send across the network. If they want to mooch from you or use your wireless network for illegal purposes (e.g. warez downloading or illegal filesharing), then they have no choice but to reveal themselves by sending traffic across in order to accomplish their objectives. MoocherHunter™ enables the owner of the wireless network to detect traffic from this unauthorized wireless client (using either MoocherHunter™’s Passive or Active mode) and enables the owner, armed with a laptop and directional antenna, to isolate and track down the source.

Water cooled PC

Have you people ever heard about $16,000 PC? No, So lets hear it now.Below is a PC which exactly cost which i have quoted before.So what exactly does spending $16,000 on a custom PC get you? This crazy PC features four quad core Opteron processors, 32GB of RAM and eight hard drives in various RAID configurations.

As you can see from the photos, the $16,000 PC features a custom water cooling system, with a massive external radiator which features nine 120mm fans.

The massive external fans run at 5V which means they are almost silent, but they manage to keep the processors running at 45 degrees C under full load and at 36 degrees C at idle.

The $16,000 PC features two VelociRaptor hard drives in RAID 1 and six 1TB hard drives in Raid 5, that is a serious amount of hardware in one single PC.

BluRay Disk Technology

Blu-ray, also known as Blu-ray Disc (BD), is the name of a next-generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world's leading consumer electronics, personal computer and media manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs will offer consumers an unprecedented HD experience.


While current optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-RAM rely on a red laser to read and write data, the new format uses a blue-violet laser instead, hence the name Blu-ray. Despite the different type of lasers used, Blu-ray products can easily be made backwards compatible with CDs and DVDs through the use of a BD/DVD/CD compatible optical pickup unit. The benefit of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm), which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it's possible to fit more data on the disc even though it's the same size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Discs to hold 25GB/50GB.

Security Auditing in Windows

Today I gonna tell you something about security auditing over Network. Being a Network Administrator security is quite an important thing to be entertained. So move on to the solution.

1. Move on Control Panel → Administrative Tools → Local Security Policy.

2. Expand Security Settings → Local Policy → Audit Policy

3. Double click on Audit object access and check the success check box. Click “OK”

4. After doing this Share the desired folder and go to Security tab, move on Advance button, go to auditing tab and click add button enter everyone as object name and click “OK”

5. Now a selection box will be displayed. Choose only the options that you need. If you want to see who delete your files and folders, just check the successful checkbox for Delete and Delete Subfolders and Files. Click OK once you’ve done your selection and also OK through all of the windows you have open.



6. To view who deleted your files and folders on your shared folder, go to Control Panel → Administrative Tools → Event Viewer and view Security. The security event logs will tell you which user deleted what files.

7. Now when someone access your shared folders and deletes a file in there, you have no problem knowing who did it.

Note:
Only disadvantage of enabling Audit is, it takes lots of CPU resources. So before implementing this just be prepare for the said issue.

Tree Size Professional

Hi, Folks i am here with an exciting new product called TreeSize Pro.TreeSize Professional is a powerful and flexible harddisk space manager for Windows 200X / XP / Vista (32 and 64 Bit). Find out which folders are the largest on your drives and recover megabytes on your disks. TreeSize Professional shows you the size, allocated and wasted space, the number of files, 3D charts, the last access date, the file owner and permissions, the NTFS compression rate and much more information of several folders or drives you choose. It also lets you search drives, entire servers or the entire network for old, big, temporary and duplicate files.

Here are some of the screen shots of Tree Size Pro:-

Screen Shots


The main window has a clear and easy to use interface which is split into the file system tree on the left and the details view on the right. Optional gradient color bars in the file system tree give a quick review. While the scan is performed you can already browse through the results which get constantly updated. Certainly TreeSize supports Unicode file- and directory names.

In the details view you will find a lot of valuable information about the disk usage like the folder size, the space wasted by the file system, the last access date, the NTFS compression rate and the owner. The listed can be sorted by any column and more columns can easily be added using the context menu.

With the pie charts you will quickly get a good impression of the disk usage. The charts can also be printed or copied to the clipboard,

An alternative graphical presentation is the bar chart. The appearance of the charts can be configured in many ways using the chart toolbar.

The Tree Map is a hierarchical chart that is able to visualize the sizes of each subfolder (not only direct child folders) of a selected directory branch.

Optionally the Tree Map can be switched to 3D mode.

The used disk space can be broken down into the file types. Filtering the file system tree on the left by certain file types will make it easy to find folders containing many of the particular file type.

Used disc space can also be grouped and filtered by users, in the same manner as the file types.

It is also possible to analyse used disk space regarding the age of files. Intervals regarding "creation date" , "last change" and "last access" are fully customizable.

The Top 100 pane provides a overview about the top 100 largest files.

Many aspects of TreeSize can be configured in the options dialog, e.g. the view, the export of data or startup options.

In the Dialog "Schedule Tasks" you can now add customized TreeSize Tasks to the Windows Scheduled Tasks.

The file search of TreeSize helps you in finding obsolete and very large files. The particular search types can be configured in detail and certain or recently changed files can automatically be excluded from the search results.

Increase the browsing Speed

While on internet, it is quite important to surf as faster as you want. Slow loading pages and slow download rate of a site put our mind on fire but don't worry here i am with a solution. First we have to understand the whole phenomena.

Domain Name System (DNS) is a database system that translates a computer's domain name into an IP address. It is easier for us to remember the domain name than the IP address for that site. Therefore this job of translating the site name to IP address is done by the DNS database.

Whenever you enter the site name like www.sitename.com, the browser will go to the site but it will look for a number like this 192.128.18.9. It is faster to look for the number. But every time your browser will look for the DNS address on the net then take you to that site. This searching for the DNS address will take longer time for the site to load. Therefore your computer saves this information in the DNS cache and it will search for this information when you enter a site name which will improve your browsing speed.

You can increase this cache size in Windows to acquire more addresses .You have to add some registry entries for this tip. Here is how

Type regedit in the Run dialog box to go to the registry.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters

In the right pane look for the following entries. If they are not present then create them by right clicking in the blank area in the right pane and selecting New --> DWORD value.

Now create these entries and change their values by double clicking on them and enter the given values.

CacheHashTableBucketSize and give a value of 00000001
CacheHashTableSize with a value of 00000180
MaxCacheEntryTtlLimit give the value 0000fa00
MaxSOACacheEntryTtlLimit with the value 0000012d

You are done. Now restart your system for the changes to take effect. Keep enjoying and don't forget to visit again.

LTO Drive Technology

What is LTO technology?

Linear Tape-Open (or LTO) is a magnetic tape data storage technology originally developed in the late 1990s as an open standards alternative to the proprietary magnetic tape formats that were available at the time. Seagate, Hewlett-Packard, and IBM initiated the LTO Consortium, which directs development and manages licensing and certification of media and mechanism manufacturers. The standard form-factor of LTO technology goes by the name Ultrium, the original version of which was released in 2000 and could hold 100 GB of data in a single cartridge. The most recent version was released in 2007 and can hold 800 GB in the same size cartridge. Since 2002, LTO has been the best selling "super tape" format and is widely used with small and large computer systems, especially for backup. Its popularity can be attributed to both the innovative technology developed as well as the attractive pricing.

LTO Drive


HP StorageWorks LTO-4 Ultrium 1840 Tape Drive represents HP's fourth-generation of LTO tape drive technology positioned as HP's first tape drive capable of storing up to 1.6 TB per cartridge while providing hardware-based encryption to enable greater levels of security and unprecedented performance.

Data hardware encryption using AES 256-bit provides easy-to-enable security to protect the most sensitive data and prevent unauthorized access of tape cartridges. By using LTO-4 Ultrium 1840 encryption, not only is data fully capable of being compressed therefore maximizing capacity, encrypted backups are completed without a loss in performance.

Capable of data transfer rates up to 240 MB/sec, HP’s exclusive Data Rate Matching feature further optimizes performance by matching host system speed to keep drives streaming and enabling the fastest tape performance in the industry.

The Ultrium 1840 provides investment protection with full read and write support with LTO-3 media, and the ability to read LTO-2 cartridge. By doubling the capacity of previous generation Ultrium drives, HP customers now require fewer data cartridges to meet their storage needs, significantly reducing IT costs and increasing ROI.

Support for Write-Once, Read-Many (WORM) media allows customers to implement a cost-effective solution to secure, manage, and archive data to meet stringent compliance regulations.

The LTO-4 Ultrium 1840 Tape Drive provides both U320 SCSI and 3Gbps SAS interfaces and supports the industry’s most comprehensive list of compatible hardware and software platforms. Each drive option includes HP Data Protector Express Software Single Server Edition backup/recovery software and the HP Data Protector Express Software Bare Metal Disaster Recovery option, as well as support for HP One-Button Disaster Recovery (OBDR) and HP StorageWorks Library and Tape Tools (L&TT).

The new HP StorageWorks LTO-4 Ultrium 1840 SAS Tape Drive models provides a 3Gb/sec SAS interface allowing direct connect to SAS-based servers.

How to make WinXP faster

Mostly people use WinXP because it is quite user friendly and popular among all and sundry. But it definitely puts your mind on fire when it got slow. So don't worry just review the following Post.

>>DISABLE INDEXING SERVICES
>>OPTIMISE DISPLAY SETTINGS
>>DISABLE PERFORMANCE COUNTERS
>>SPEEDUP FOLDER BROWSING
>>IMPROVE MEMORY USAGE
>>OPTIMISE YOUR INTERNET CONNECTION
>>OPTIMISE YOUR PAGEFILE
>>RUN BOOTVIS - IMPROVE BOOT TIMESREMOVE THE DESKTOP PICTURE
>>REMOVE FONTS FOR SPEED
>>DISABLE UNNECESSARY SERVICES
>>SPEEDUP FOLDER ACCESS - DISABLE LAST ACCESS UPDATE

You have to do some more thing with the above said

1. Click on Start, then Run, and type "msconfig". Wait for a new window to pop up.
2. Look under the "BOOT.INI" tab. You will see a box labeled "Timeout:", and a numerical value. By default, it's 30, which means 30 seconds of wait time before boot. This can be changed, using 3 seconds. (Note: if you have more than one operating system, this means the wait time to startup to the highlighted OS. you might want a bit more than 3 seconds)
3. Delete the temporary files periodically from your computer to make the applications run faster. Type %Temp% in the run dialog box by clicking on Start -> Run, and click on "OK". You will see an open folder with many files. Click on the Edit menu and click on Select all and then click on the File menu and select Delete. Note: Always confirm that the folder which is opened has a temp on the top of menu bar and the folder indicates that it is a temporary folder.
4. Perform a scandisk to see that your computer hard drive is in healthy condition and it helps your computer run faster.
5. Always perform a disk defragmentation at least once in a month. start the disk defragmentation from the system tools available in the accessories from the start menu. it takes a longer time and it is advised not to run any applications in the computer including the screen savers, while running disk defragmentation.

Hibernation

After you have done all this, another method you can do is to allow the computer to hibernate. Hibernation closes and opens Windows faster than normally. However, Hibernation is not a good long-term solution, as it continues to waste electricity.

1. Go to Start->Control Panel->Power Options. Click on the Hibernate tab.
2. Click on the box that says "Enable hibernation" to check it.
3. Click on the Advanced tab and change the Power buttons options if you want to hibernate by pressing the sleep button or the power button. Otherwise, holding the Shift key while in the Turn Off Computer menu will give you the option to hibernate.
4. Restart your computer every week or so to clear your computer.

The power can then be completely turned off, even at the socket so that no power is wasted.

Prefetch

1. Simply browse to the windows folder (Ex: C:\Windows) and under there you should see the prefetch folder. Go into the prefetch folder and delete all the files (Careful! It should look like this c:\windows\prefetch). We need to edit a registry key to tweak it. Open regedit and browse to this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters

Under this key you should see a value named: EnablePrefetcher

It has 4 possible values:

0 - Disabled : The prefetch system is turned off.

1 - Application : The prefetch only caches applications.

2 - Boot : The prefetch only caches boot system files.

3 - All : The prefetch caches boot, and application files.

We don't want to disable it entirely. This would actually make boot times *longer*. This is because this feature is also used to speed up the loading of boot files. That is why we are going to pick the number 2 option. It allows us to keep the advantage of caching system files, without continually clogging the system up with applications.

Set the value to 2 and reboot.

The 2nd time you boot it should boot much faster. Remember that the side effect is that launching individual applications once windows has loaded will now be slightly slower.

* When installing new software choose not to add the program to the startup folder.

* Regularly check to see what programs are running from your startup folder as malicious programs such as spyware may have installed itself without your knowledge.

* If you accidentally uncheck a program, just retrace the steps above and recheck the program and restart your computer.

* Adding more RAM to a Windows XP computer helps it boot faster, and since RAM prices are very low these days, it's an easy way to boot faster.

* Visit http://www.Sysinfo.org and look up the program and its details you don't know what one of the listed programs do. Alternative sites: CESAM Startup Files Database, Bleepingcomputer Database.

BIOS Upgrade
The BIOS is a bit of software that sits on your computers motherboard and controls how each component talks to each other. It is a good idea to upgrade this if possible to the latest version as you could see many benefits. A BIOS upgrade will help the motherboard to be more efficient in the way that its components talk to each other.To upgrade your BIOS find out what motherboard you have (You can do this by looking in the manual that came with your computer, or you can look at the screen that first shows when you turn on your computer, it should like the make and model on there) Then when you know what motherboard you have go to the manufactures web site and search for the latest update. Be aware that BIOS updates could possibly harm your system if not installed correctly, Computing-Tips.com can not be held responsible should you cause harm to your computer.Next go in to your BIOS (Do this after you have upgraded BIOS as setting might go back to default settings if you upgraded) Make sure that all cache settings are enabled especially on the CPU. Disable any devices you don’t use, for example if you dont use USB disable it. Devices will use up valuable memory when your system has booted in to windows xp. You might also think of disabling, floppy drive, infer red, LPT / COM ports, and so on

You can speed up the boot process by enabling “Rapid Bios Boot” or “Fast/Quick boot”. Also turn off auto detection of IDE devices and detect them manually. Set System and Video BIOS Cacheable to OFF as well as Video RAM cacheable to off, as these are legacy operating system DOS settings. Disable GUI Options
1. Right-click on the desktop and click properties.
2. Click on the “Appearance” tab at the top.
3. Click the “Effects” button
4. Uncheck “Use the following transition effect for menus and tooltips
5. Uncheck “Use the following method to smooth edges of screen fonts” - (unelss using an LCD monitor, in which case, check this)
6. Uncheck show shadows under menus
7. The others don’t really matter.
8. Click the “OK” button
9. Back at the “Display Properties” window, from the “Windows and buttons” select menu, select “Windows Classic Style.”
10. Click the “Apply” button.
11. Click the “OK” button.Clean Your Registry
The REGCLEAN utility from Microsoft cleans your system registry of unnecessary entries that are created when you install or remove programs on your computer. Sometimes an “orphaned” registry entry can confuse Windows during startup and cause a delay. And in general, slimming down your registry will make Windows run faster. You can download REGCLEAN here. Note: This program is no longer officially supported by Microsoft, but many users report that it works fine on Windows XP systems. You can also try RegSeeker which is a highly rated registry cleaner.

HouseKeep Your Hard-Disk
Over time your hard-disk will clutter up and you will need to clear this down and also run some checks to make sure everything is running okay. The more data that is stored on a hard-disk the slower it will take to access data as it has to search through more files. So here are a few things to check, check them in the order belowClean Your System From Virus’s and Spyware
Make sure you have an updated virus scanner with the latest virus definitions database. Do a full search of your system and make sure all visrus’s are cleared. Also get hold of a program that will search and remove spyware, I recommend Adware by Lavasoft, take a look here. Delete Internet Related Files
For every website you visit your computer will download files and store them on your computer (Cookies, Temp Internet Files, Form Cache, and so on) To clear these down right click on the IE icon on your desktop and select properties, Under browsing history click delete, then in the next window click delete all.Delete Temp Files
Most programs you use will leave *.tmp / *.temp files on your computer, Over time these files will pile up and can consume alot of disk space. To clear these files down click start > run and type in CMD then press enter, A black window will pop up. In this window type

Del /a /f /q /s C:\*.tmp and Del /a /f /q /s C:\*.temp

Then press the enter key. If you have 2 partitions repeat this process for the other partitions, Replace C: with the letter of your other drive, for example Del /a /f /q /s D:\*.tmp if you have a D: drive. Be careful when doing this, if you enter the wrong command it could delete some system files and cause windows xp not to boot.

Remove Unnecessary Software
You may have a bunch of software packages on your hard drive that are no longer needed, or they were gratuitously installed when you downloaded some other package. Toolbars, file-sharing programs, free email enhancers, online shopping “companions” and download managers are notorious for this practice. These uninvited guests can put a big drag on your startup time, cause web pages to load slowly, and generally bog down your computer. Go to Control Panel, then Add/Remove Software to see what packages are installed. Remove the ones you know you don’t need, and do a web search to learn about the ones you’re not sure about.Empty The Recycle Bin

Double click on the recycle bin icon on your desktop, Delete all the files you dont require, be aware if you delete files from here you can not get them back.

Run A Check Disk
Now its time to check if there are errors on your hard-disk. Double click on the my computer icon on your desktop, right click on the disk that says C: and then select properties. Click tools tab > Check now then tick the 2 boxes and hit start, You will get a message pop up, asking to perform the check disk on next reboot, click yes. Now reboot your system and let the check disk run. The checkdisk will tell you if it finds any errors on the disk and it will also attempt to repair them. Perform this action for any other hard-drives you might have.

Run A Defragmentation
A defrag will re-arrange where the files are located on your system, it will move the files to make sure you get the best performance when access files. For example it will move all the system files to one part of the disk, so when the system needs to access system files they are all in the same location and the hard-drive does not need to jump around the disk as much to access what it needs.To run defrag double click on the my computer icon on your desktop, right click on the disk that says C: and then select properties.Click tools tab > Degragment now. Then select each partition you have in turn and click the defragement button. You will get a report of what has been done when it has finished.

Disable System Restore
System restore will take up resoruces such as memory and hard-disk IO. Personally I have been using windows xp ever since it came out and I have never used system restore. If you are going to disable the system restore make sure you backup important files to anther disk such as USB stick / CD-ROM / Tape drive and so on. To disable system restore in windows xp do the following
1. Right-click ‘my computer’ and click properties.
2. Click the “System Restore” tab at the top.
3. Check the box “Turn off system restore on all drives”

Configure The Paging File
When your system runs out of physical memory windows xp will use something called a paging file. A paging file is basically a file that sits on your hard-drive and will be used as memory should your system run out of memory. Ideally you dont want to run out of physical memory because your system will slow down if it uses the paging file. So we need to make sure we configure the paging file correctly incase it is needed.To configure a windows xp paging file right click on the my computer icon on your desktop, click advanced tab, then under the performance section click on the settings button. in the next window click on the advanced tab then change button. You dont want windows to automatically handle the size of the paging file so select custom size and then enter 2048 for the initial size and also maximum size. Disable Un-needed Services From Starting
When your system starts it loads certain services which eats up valuable memory which your system might need. The more services we stop from starting the more memory we can make available to the system. To disable a service do the following, Right click on the my computer icon on your desktop and click on manage, Double click on services and applications, then services. To disable a service double click on it and where it says startup type simply select disable, The service will then get disabled on the next system reboot. Be careful if you disable a service that the system requires you could cause your system not to boot, Computing-Tips can not be held responsible if you damage your system. I recommend that you can disable the following services-Alerter, used to send popup administrative alerts, These alerts can also be viewed from the eventlog if this service is disabled.
-Clipbook, If you disable this service you will not be able to copy and paste text / pictures and so on. Its up to you if you want to disable this.
-Computer Browser, This is used to keep a list of other computers on the network
-Error Reporting Service, Turn this off if you dont want errors to be reported.
-Event Log, All errors are written to an event log, if you disable this service nothing will be written to the log.
-IMAPI CD-Burning COM Service, If you disable this service you will not be able to burn CD-ROMs
-Indexing Service, This service should speed up access to frequently used files. In my experience it is not worth using it as it uses a lot of memory and slows down your whole system as a result.
-Messenger, If you disable this you will not receive any windows popup messages.
-Net Logon, This service is required if your computer is in a domain, If the computer is not in a domain disable this service.
-NetMeeting Remote Desktop Sharing, Disable this if you dont want to share your desktop with remote users (Support for example)
