Can't login to XP

By Creay ·
I have a pc running Windows XP Pro on a domain. Since yesterday I am unable to login to this pc or on the domain. It says incorrect username and password. At the logon screen under options, the selection for 'this pc' or 'domain' is not there. Cant log on with any username even administrator. Have run password changers etc, no luck. Any advice.

Have you tried to unplug it from the network before you log in?

Yes I have even disabled the onboard lan and replaced it with another lan card.

If there is any important data on the disk, get it off, and then reimage the HD. Something is corrupt, and you could spend more time than it is worth very quickly.

Can you boot with the CD-ROM to the recovery concole, and login that way with the administrative password? This is one way to recover important data.

If even this does not work then try some of the tools on a live Linux CD-ROM like PHLAK ( or Knoppix (

It's probably little consolation but I had exactly the same problem after getting the latest M$ updates on 2-14-06 that required a reboot. I tried the same as you to no avail.

Apparently my PC did an Windows XP autoupdate to get 1 update that failed to install and after automatic restart overnight I couldn't log on 2-15 AM.

I can't really lay it off to an update though because I used System Restore and reinstalled a recent clean back-up copy of the Registry (in Safe Mode) which, I think, should've removed any update problems.

I ended up having to restore the drive from a Symantec Ghost back-up that I made just before using M$ update. After the restore, I got the updates again on 2-15 and everything worked fine.

Was I hacked somehow at some point before getting the updates? Did M$ correct their updates between the time I 1st got them and the 2nd time( 8 hours before I discovered the problem)? I don't know.

It was interesting, to me, that like mine, two of the other PC's on my home network had 1 update that continuously failed to install on 2-14. On 2-15 the other 2 installed the update with no problems as did mine.
