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.
