I have a 2ndry DC that needs to come out of service to be reformatted. Dell only put a 12 GB partition on it. As of now it is working fine and DNS is pointed to itself since replication has been fine. Should I point it back to the primary DC DNS or is it ok pointing to itself before DCPROMO to demote it? Also its a global catalog server now, should I uncheck it first? Do any records need to be cleaned up after in DNS?
