If this value has the data of 00 00 00 00, change it to 01 00 00 00Remember to reboot the computer.

Computer keeps disconnecting from the Internet

Go to IE tools/internet options/connection/dial up settings/advanced dial up settings. Make sure that disconnect when connection may no longer be required is turned off, and that the option to disconnect if idle is turned off as well. Later Windows versions have an option to disconnect when connection speed drops below a certain percentage. Turn that off.Outlook Express options can cause problems if the programme is running. Go to Outlook Express, tools/options/connection and make sure *connect to this account using* is not selected for each mail and news account. Make sure there is no conflict in account settings - each account should show the connection option of *any available*.Next in Outlook Express go to tools/options/connection and turn off *hang up after send/receive*.

I dont hate Mozilla ! Orkut is banned !!!!!

I was asked by my friend that he is the only user in his computer, his account is having administrative rights, but he is not able to open Orkut, and it says Orkut is banned. Another friend had told that he is not able to use Mozilla Firefox and it asks him to use Internet Explorer. I just told it must be some virus, but really didn't care much about that. But none of the antivirus software could detect or remove this malware.

My friend had given me a pen drive. I remembered it while browsing net on Firefox. When I put that in my PC and double clicked, it didn't open. I knew at once: I had activated a virus. But I didn't have any idea about the kind of virus that might have come to my PC, until I switched back to Firefox. Immediately a message box was displayed: I DNT HATE MOZILLA BUT USE IE OR ELSE... with title as USE INTERNET EXPLORER U DOPE. I just remembered the experiences of my friends. I tried to locate the virus by running the Task Manager. But there were no suspicious entries there. I had to bow the owner of the virus. I used Internet Explorer to search about it. The first entry in Google took me to the Mozilla Forum page, and after going through some pages, I came to know that the same virus also displayed another message when you opened Orkut. Orkut is banned you fool, The administrators didnt write this program guess who did?? MUHAHAHA!! with title ORKUT IS BANNED. Well, a similar message was displayed for YouTube also. So I went through all the posts, and finally found a solution given here:


Press CTRL+ALT+DEL and go to the processes tab


Look for svchost.exe under the image name. There will be many but look for the ones which have your username under the username


Press DEL to kill these files. It will give you a warning, Press Yes


Repeat for more svchost.exe files with your username and repeat. Do not kill svchost.exe with system, local service or network service!


Now open My Computer


In the address bar, type C:\heap41a and press enter. It is a hidden folder, and is not visible by default.


Delete all the files here


Now go to Start --> Run and type Regedit


Go to the menu Edit --> Find


Type "heap41a" here and press enter. You will get something like this "[winlogon] C:\heap41a\svchost.exe C:\heap(some number)\std.txt"


Select that and Press DEL. It will ask "Are you sure you want to delete this value?", click Yes


Now close the registry editor.

Now the virus is gone. But be sure to delete the autorun.inf file and any folder whose name ends with .exe in the pen drive.

The Windows XP File Systems

When installing Windows XP from scratch, it prompts you to select from two different file systems: FAT32 and NTFS. As expected, it gives no real reason why you should select one or the other, and defaults to NTFS.


FAT32

If you're installing on a dual-boot system where you would have a FAT32 partition (default type for Windows 98 and SE for partitions over 2GB), you may run into problems depending on your situation. The FAT32 file system was created when the size of hard drives exceeded 2GB. The previous file system for DOS and Windows 95 was FAT16, which offered at most 2GB of allocation on your hard drive. This of course is useless for today's hard drives when you can't find anything under 10GB anymore. Where FAT16 allowed a 2GB maximum, FAT32 only allows a 32GB maximum. If your hard drive is over 32GB, you'll have to split it into separate partitions, or use NTFS.


NTFS

NTFS was introduced with Windows NT. Among the reasons why it was introduced, it allowed partitions greater than what's even offered today, and boasts better performance and security. Focusing on security, it's possible that while an NTFS hard drive is secure when running Windows XP, there's no easy way to get back into the hard drive if you boot from an emergency floppy that only sees a FAT16 or FAT32 partition, such as what you'd get from a 98 or ME emergency floppy. The security in NTFS actually prevents you from circumventing its own file system from a boot floppy. This means that if for some reason your hard drive becomes unusable and you need to move data off of it, the task won't be as easy as it was when using Windows 95, 98, and ME. The solution that the user has in this situation is to boot from the Windows XP CD and run a repair on the hard drive. This should fix any problems the user had with the system and bring it back to a bootable state. The other issue is in dual-boot situations. Running under NTFS, you can see FAT16 and FAT32 partitions, but if you boot back into Windows ME, you can't see the NTFS partition. This is a problem if you downloaded something to your XP partition and you want to move it to your ME partition while running under ME. Also, if you upgraded ME to XP and you convert your file system from FAT32 to NTFS, you cannot go back to Windows ME since ME can't run under NTFS. However, only NTFS allows you to set permissions on individual folders so that you can control who sees what.


Converting from FAT32 to NTFS at a later time

If you want, under Windows XP you can convert your FAT32 partition to NTFS using the following command from your Command Prompt:


convert c: /fs:ntfs


Conclusion

With all this information, find what suits your needs and go with it. If you're the kind of person that backs up regularly, go with NTFS. Same if you want to use a partition over 32GB without partitioning. If you want to play it safe, or if you want the ability to transfer files from one partition to another under a dual-boot situation, stick with FAT32. If you want to read more about these file systems, Microsoft has an excellent article on their web site.

Classic Look Make XP look just like older versions of Windows

If you're like me, you probably have grown way too close to the familiar Windows interface. That's OK. I don't adjust well to change either.

After installing XP you may notice the revamped interface looks nothing like the old one. I was completely thrown back when I tried using it for the first time, but I suspect that over time the new interface will begin to grow on you as it has with me.

Therefore, to ease your transition to the new OS, make a simple adjustment to XP to give it that classic look.

Here's how to do it:


Right-click your Desktop and select Properties.

On the Desktop Display properties, click the Appearance tab.

Under the Windows and buttons pull-down menu, select Windows Classic.

Click Apply to see your new look.

Click OK to close the Desktop Display properties.

Adjust various visual effects

1. Open up the control panel

2. Go under system and click on the advanced tab

3. Click settings under Performance options

4. You can now change various graphical effects (mainly animations and shadows)

Windows XP and Symmetric Multiprocessing

Symmetric multiprocessing (SMP) is a technology that allows a computer to use more than one processor. The most common configuration of an SMP computer is one that uses two processors. The two processors are used to complete your computing tasks faster than a single processor. (Two processors aren't necessarily twice as fast as a single processor, though.)


In order for a computer to take advantage of a multiprocessor setup, the software must be written for use with an SMP system. If a program isn't written for SMP, it won't take advantage of SMP. Not every program is written for SMP; SMP applications, such as image-editing programs, video-editing suites, and databases, tend to be processor intensive.


SMP in Windows XP


Operating systems also need to be written for SMP in order to use multiple processors. In the Windows XP family, only XP Professional supports SMP; XP Home does not. If you're a consumer with a dual-processor PC at home, you have to buy XP Professional. Windows XP Advanced Server also supports SMP.


In Microsoft's grand scheme, XP Professional is meant to replace Windows 2000, which supports SMP. In fact, XP Professional uses the same kernel as Windows 2000. XP Home is designed to replace Windows Me as the consumer OS, and Windows Me does not support SMP.


The difference between XP Professional and XP Home is more than just $100 and SMP support. XP Professional has plenty of other features not found in XP Home; some you'll use, others you won't care about. Get more information on the differences by reading this article.
