I have a VM host that crashed, one of the guests ran AD/DS. I have a standalone AD/DS box also. I did the failover of the guest with AD/DS on another host VM server and the replica boots fine but permissions don't allow users to access network printers or WSUS (also on that VM). Can I disjoin the replica and rejoin to see if that fixes permissions or should I try something else first. If I disjoin do I need to do dcpromo and demote the AD server?
