I have two dells with the same exact problem ( go figure ) They both had missing the Windows/System32/Config/System file..i managed to restore them both with the command prompt...windows boots...then both of them get the lssas.exe (system error)" When trying to update the password, this return status indicates tha the value provided as the current password is not correct"..the computer doesnt even stay on long enough...maybe just 5 seconds..ive read that this might be the sasser worm...but des anyone know if this is a legitimate system error...or just a virus in disguise.
