lsass.exe system error - the specified domain name did not exist

[Guest SmoothOper8r]

One of the workstations on my network booted up this morning with the

following message:

 

lsass.exe system error - the specified domain name did not exist.

 

This workstation has updated virus scanning software installed on it and has

been updated with recent windows updates.

 

I tried running the repair tool off of the XP pro disc and i get the same

error. Any ideas on how I can fix this problem without the ability to boot

windows (in safe mode or otherwise)?
