At a site and on a Win2K8 AD there is a DC still listed in Active Directory Sites & Services console that was retired years ago. All of the FSMO roles, Global Catalogs, DNS Servers, etc... have long since been migrated to a new machine or machines. This no-longer-used DC does not show-up in AD Users & Computers, Domain Controllers, not in the DNS Server entries for the domain, and not in any WINS Server databases. Is it okay to just right-click on this long-since-retired DC and delete it ? Are there any other places I should check to see if this older DC is still listed ? Any other best practices or recommendations before I just delete it ? Or since that older server has not been in existance for over two years is this just as simple as right-clicking on that one entry in AD Sites & Services and deleting it ?
