Windows

Log on locally to the PDC as Administrator (or equivalent). Start User Manager for Domains, navigate to the locked user account and unlock it. Force a replication between the PDC and BDC. Try to log back into the BDC. If that doesn't work, you could also try creating a new administrator account from the PDC, replicate, log in to the BDC with the new account, and unlock the locked account. If you still cannot unlock the locked account or log in to the BDC, you will need to backup the server, and rebuild it.

This is the very reason why there should be at least one "backup" user account that has "God" administrator permissions on any network.

Do You have an Emergency Repair Disk, then you could try running the install cd and go to the repair option. This should allow you to repair the relevent files for administrator account. If you don't have a ERD then you can still do the repair butyou may have to reinstall some of your software.

If you have a user account with admin rights to the local machine (the BDC) log in and reset the locked out account. Create or promote a user account as a domain admin and unlock the account.
