I am in process of decommissioning our old Server 2003 DC. I have already ran DCPromo. I am trying to clean AD. We have three active 2008 domain controllers. I have already transferred all the FSMO rolls from the 2003 server to one of the 2008 servers. We have an Exchange 2003 SP2 server. The old 2003 domain controller has no more rolls.
I am trying clean AD/DNS of the old DC. When I went to AD Sites and Services and expand Default-First-Site-Name > Servers then try to delete my old DC I get an error when trying to delete it saying this Object contains other objects.
Before my time here there was an Exchange 5.5 and then it was upgraded to 2003. I have not touched Exchange. The Global Catalog now resides on other domain controllers. Am i ok to delete this?
