Clear domain group policy on computer without connecting DC

[guest]

Q: Our DC died. You created a new domain and want to join all workstations to the new domain. However, the old domain policy apply to the computer and we can't do it. Logon local admin doesn't help. Is there a way to clear the domain group policy without connecting to the domain?

A: Try this:
Open Regedit.

Backup your registry.

Delete the HKLM\Software\Policies\Microsoft Key (looks like a folder).

Delete the HKCU\Software\Policies\Microsoft Key.

Delete the HKCU\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects Key.

Delete the HKCU\Software\Microsoft\Windows\CurrentVersion\Policiess Key.
Exit the registry and restart.

Note: HKLM = HKEY_LOCAL_MACHINE & HKCU = HKEY_CURRENT_USER

Note 2: The registry is and can be a dangerous place.
