I have a problem with a desktop computer running Windows XP.

We awoke this morning to find it rebooting over and over in a loop, never getting past the loading screen. We managed to get in with safe mode, and I turned off the automatic reboot option so we could see the error, and here it is:

STOP: c000021a [Fatal System Error]The Window Logon Process system process terminated unexpectedly with a status of 0xc0000022 (0x00000000 0x00000000).
The system has been shut down.

Can anyone offer advice on how to fix this? Thanks.

What did you do the day before the error started?

What did you do the day before the error started?

Installed the latest World of Warcraft patch and played that for a bit, maybe some internet browsing. Not much else.

Try booting with Last Known Good Configuration.

If that doesn't work, boot back to Safe Mode, uninstall the new WOW patch and see it that helps.

Do you have a reliable antivirus software installed? Is it current and when did you last run a full scan?

I'm trying to relay this back to home, I'm at work right now...

He says the last thing that happened was this morning right before it started the loop, a virus tracker (not sure which one) found a virus in winlogon.exe and he hit fix or heal, which made him reboot, and that's when it started looping.

Tried the "last good configuration" thing and it didn't work. I'm planning on working on it more tonight when I get home since he's having a hard time with the command line stuff.
