Windows XP Logs Off As Soon As I Log In

I have an issue with a PC on my domain.  Windows XP Pro SP3.  When I login - it logs right back off.  I have researched the knowledge base and followed the suggestions with no results.

1:  I connected to the registry via the network and looked for key corruption in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\.
Key "userinit" was set to C:\WINDOWS\System32\userinit.exe,
2:  Did a repair install.

I still have the problem.
Normally I would just wipe it and reimage, but this laptop belongs to the CFO and it would take days to rebuild.

Any help would be appriciated,

Are you sure this is not due to a virus, I had a similar experience not long ago, some virus and spyware,

After running the antivirus and malarebytes pc wouldn't log in.

I was able to run a reinstall repair without wiping anything.

if the laptop has sp3 already you may want to make a cd with sp3 using nlite otherwise you may run into some issues

The laptop had Antivirus 2009 on it, which I got off with Malwarebytes.  The problem started after that.  I did do a reinstall repair, but the problem still remains.
Similaro problem I had, did you do a reintall repair with a XP CD with SP3 on it ?

Di yu try to log in in to the laptop locally?
Hi,

Try the following

1. Download Avast! Anti-Virus and CCleaner. You can get them from avast.com and download.com
2. Install CCleaner
3. Boot into Safe Mode with Networking (F8 on startup) and install Avast!. Update Avast!. (It will say it can't run on a computer with Symantec. Click OK on this message, we will be scanning out of windows so there won't be any conflict during the scan. Just remember to uninstall Avast! once you are finished with it.
4. Run CCleaner. This will delete all temp files from the system.
5. Schedual a Boot Time Scan with Avast!
6. Unplug the computer from the network
7. Restart

Avast! is the only anti virus software that I know of that can do a virus scan out side of windows. I use it regulary on my client's comptuers and have had great luck with it.

Once the Boot Time Scan is finished I would:

8. Put a Windows XP CD in the drive and run SFC /Scannow from the run command (Start -> Run) This will scan all windows system files and replace any that are corroupt.
9. Plug the computer back into the network
10. For good measure download Malware Bytes from malwarebytes.com and scan for spyware.
11. Restart as nessary
12. Uninstall any unnessary software (Avast, CCleaner, Malwarebytes)

Cheers,
Perry

Windows XP Login Logout Loop (Virus)
What perry says makes a lot of sense but sometimes with this problem you can not even login on safe mode, it will just login and logoff right away.

You can boot to the recovery console and try do a file system scan

good luck
