We recently had to take our 2003 domain controller (w1604-12) off the network and our backup vendor brought a virtual DC up incorrectly and it registered with the name w1604-12-old as a domain controller. We got the original back working but when we added it to the network. Now we receive a "Interface is not known" error when trying to connect to the DC. It also will not start the netlogon service. Please Help!!!
