I am trying to remove a dc from a 2003 active directory domain. I have 2 dc's in my domain and I need to remove one of them. I have installed VMWARE ESX server on one of my boxes that had my domain controller on and I have reinstalled Windows server 2003 with the same ip address and dns name as the old dc. I did not demote the DC before installing the ESX server so it is currenty still in active directory. I have found a procedure at http://www.petri.co.il/delete_failed_dcs_from_ad.htm
that shows how to remove the inactive dc from the domain. The question that I have is do I need to do anything special before I promote this box as a DC in my domain. When I tried before it give me an error that is could not join the domain because the user already existed (Like I said before I am using the same dns name as old server and it is still in AD). Also this box was a DNS server for AD so I assume I need to remvoe it there also. I probably could rename the computer and everything work out ok but I didnt know if this would cause problems in Ad down the road.
