When I click on Start->Logoff, rather than logging off and going back to the CTRL+ALT+DEL logon screen, the entire computer shuts down and powers off. This doesn't happen with other accounts (even other domain accounts) so it's something specific to my user.
This is on Windows XP. Is there a registry setting that controls this sort of behavior? Thanks!
Updates:
As for virus scan, there is a virus scanner running on the computer. If I try to exit it, it wants a password. If I try to terminate the process using Task Manager, I get an "Access Denied" error (It's running as SYSTEM). So I can't test if that's the culprit.
Using the Shutdown command actually works. Running shutdown.exe -l will log me off and take me back to the logon screen - so this means it's something with the actual Logout button the Start Menu itself. I guess I can use this as a workaround.
I also looked in C:\WINDOWS\system32\GroupPolicy\User\Scripts\Logoff
and there are no files in that directory.
