12 Mar: The security account manager (SAM) has determined that SID is already in use in the Forest

The security account manager (SAM) has determined that the security identifier (SID) for this computer is already in use in the Forest you want to join. This can happen when restoring an Active Directory Domain Controller with an improper backup. Reinstall the operating system on the local AD DC to obtain a new SID.
