win xp rebooting at login screen

[RandyRiegel]

I have a Windows XP machine with SP1 on it. I had SP2 on it but was having trouble mapping my samba drives after installing it so I uninstalled SP2. Ever since I uninstalled it my computer will boot to login screen then reboot automatically, over and over again. I tried to go into safe mode to try and fix the problem and it locks up every time. Any ideas?

There is non-virus malware going around now that does a similar thing to this. Read this whole article:

A second reason can be security polciy settings:

The latter links are more inclined to be the problem if it gets as far as the login screen.
