I don't know.....*sigh*
I'm barely understanding this, from what I have found so far there is a file named 'sam' in the system32/config folder that contains a 'hive'?? of users and passwords, whats in there is corrupt, because i just tried a few tools off of hiren's and none of the successfully changed the password, 1 was able to find the sam file, open it, view the users, and then said it changed it to 'test' like i wanted, but when i rebooted it refused to take 'test' as the password and still has the guest user as disabled, which i unset.
It probably doesn't help that these are raided sata drives that the os is on.
