Ravi,

I haven't seen this for a while. This is quite likely an infection with Sasser
or a similar worm. This happened because you have not been using an internet
connection firewall, and have apparently neglected to install the critical
updates available from Microsoft.

Disconnect this computer from the network. It isn't helping anybody, by it
being connected.

If your computer is constantly attempting to shutdown or reboot:
Start - Run, type "shutdown -a", and hit Enter.
That should halt the reboot. Now fix the problem.

Immediately turn-on Windows XP's built-in Firewall:

Better yet, implement layered security:

A special note if you use AOL:

America Online installs its own connection settings that override
the ones that come with Windows XP. America Online's
connection settings don't include a way to turn on Windows XP's
built-in firewall.

I also suffered from the same problem,you got to update ur XP pro to
SP2(service pack 2) this will surely fix the problem,or else you may visit
this and download the file and scan your PC,that virus(Sasser-which is
causing the reboot) will be removed
