The specified domain did not exist

insuremce used Ask the Experts™
We have just booted one our laptops that runs XP Pro. On complete of boot when windows comes up and says "windows is starting up" an error box comes up - "lsass.exe - system error" with the error: "the specified domain did not exist." ok is the only option and as soon as it is clicked the PC reboots.

I have tried going in to safe mode to fix the problem but the error still appears at the same point.

Hi fm250, I have looked at the posts and I would imagine they would work, if I knew the administrator password for the windows installation. A nightmare, it is not what one of our usual passwords.

Is there any way to get around the passwording without needing to boot windows.

Hi Adam,
that is another story then. but you may try this one:

instead of installing another os you can just take the hdd and put it as a secondary hdd on anther system. if you are going with that method.
but I would recommend going with linux one.


somehow guessed the administrator password in the end and the accepted answer worked.


Glad that it worked for you.
