Yes, you broke the domain connection and therefore can't log into your domain user account. Most domain member computers don't have a local user account and of course the local administrator is password-protected. If this is a laptop that you use at work, take it to your IT Dept. and have them fix what you did and rejoin the machine to the domain. They can help you do whatever it was you were trying to do with this laptop at home (probably trying to print?)MS-MVP - Elephant Boy Computers - Don't Panic!
