Now if the domain controller has been unplugged and offline for more than the tombstone lifetime, (60 days for Windows 2000, Windows 2003 SP0, or 180 days for Windows 2003 SP1 and all newer operating systems), you will need to run a Metadata Cleanup to remove the DC.This is due to the scavenging period that AD will keep deleted objects or objects that have not been in communication with such as a domain controller.Open Active Directory Sites & Service, Drill down and expand the AD Site name the domain controller exists in Click on the DC’s name In the right window pane, you will see “NTDS Settings”Right-click NTDS Settings, Choose Properties Under the General tab, uncheck the Global Catalog checkbox 5.If this domain controller currently holds one or more FSMO operations master roles, transfer the operations master roles to another domain controller before demoting it.
