Lsass.exe error - XP laptop won't boot up
Posted on 2011-10-28
Hi Experts, I've got an old Compaq Presario laptop running XP Home (SP2) that certainly is well past its Best Before date, but cheap like I am, I'm trying to squeeze some more use out of. The other day when I tried to boot up, it gave this message as it was just starting to bring Windows up:
lsass.exe - "An invalid parameter was passed to a service or function"
... followed by an OK button. When clicked, it just goes back to booting up and then gives this error over again. I do have a "BartPE" CD that has saved my butt numerous times and hoped that it would do so again. I booted up using that and once in that environment did a full CHKDSK \R. It indeed found some corrupted stuff that it rectified, then I attempted to boot again. This time it was again an Lsass error, but with a different message:
Lsass.exe - "when trying to update a password, this return status indicates that the value provided as the current password is not correct"
... and it won't allow me to get any further than that. Googling around I found a site that said it could be a virus and it suggested to click START then RUN and type in a certain command ("shutdown -a") during the 60 seconds before the virus shuts your system down again - but I never get as far as being able to access START, so maybe it's not that virus. Any thoughts please anyone?
