Startup begins then immediately logs off

[Andy]

When I start up the pc, I get a user icon which says OEM
user. When selected, the PC begins to log in and then
immediately logs off. I cannot break the cycle.

Thanks for the help

Hi Andy,

A User Logon Request Is Rejected Without Any Messages
http://support.microsoft.com/?kbid=313322

If the above is not the case, this does work and has been verified:

The problem turned out to be that the Winlogon userinit entry was set to
"wsupdater.exe," and not "userinit.exe,".

Verified by Rick Lewis:

Place your XP CD in and navigate to the Recovery Console.
Change the C:\Windows prompt to: C:\Windows\System32 and copy userinit.exe
to wsaupdater.exe

Reboot into Safe Mode and modify:

change userinit in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon from wsaupdater.exe, to userinit.exe,
