Logon and them immediate logoff ???

[geno368]

I am trying to boot up a PC that allows me to log on and then I get a brief(1 sec) desktop background and then goes straight to logoff. It's running XP Prof and I went to recovery console and did a chkdsk /r and it said it fixed 1 or more errors. I ran it again and it was clean. It still won't work even in safe mode. How can I fix this?
Thanks

I had something like this happen when users got viruses on their computers. Logon and then immediate logoff.

I think I could still log on as administrator in Safe mode, though.

I had the same problem and had to expand the userinit.exe file from my XP disc to c:\windows\system32.

logs you on loads personal settings then logs you off?

A second reason can be security policy settings:

Did you perhaps clone this hard drive from another hard drive. If so, there's a reason for that happening.

This registry setting needs to be cleared out before cloning. I had this happen to me using Ghost.
HKEY_LOCAL_MACHINE\System\MountedDevices

Remote to it from another machine, create another user and log on as that new user.
