Good Evening- I'm having a problem removing my old 2003 domain controller from my domain. I current have a windows 2003R2 SP2 Server that is the original domain controller. Next I have my new 2008R2 server that is my new domain controller. I have ran all the adprep commands to prepare the domain, forest and gpo for the new 2008 domain. Currently the domain and forest is at 2003 level. I have moved all the fsmo roles to the new 2008R2 server and it is the GC also,
So my problem is when I run dcpromo on my original domian controller it think it's the last domain controller on the domain and can contact any other domin controller.
As a test I create a new 2003R2 server, made it a domain controller and moved all the FSMO role to it. Then I tried to dcpromo the original controller to remove it but it still thinks it's the last DC on the domain.
Can someone please get me back on track or give me some idea on what is goning on?
