When trying to join a Windows machine to a zone, getting the below error.
Failed to Enable Service
Reason: Directory Object already exists.
It is very likely that the Windows machine had been previously been joined to the zone in question and the ServiceConnectionPoint (SCP) did not get cleaned up when the machine was initially removed from the zone.
