I transferred AD and DNS to a new domain controller. Then changed the IP and name of the old one and shut it down. I changed the new server's IP to the old one, then tried to change the new server's name to the old one. But when I try to see AD, I am getting the following message: The following Domain Controller could not be contacted: ED01. The interface is unknown.
Prior to changing the IPs and names, I had the AD working after the transfer with the old server shutdown. I tried to "go back" by putting the new server's IP back to what it initially was. But I was unable to change its name to its initial name (so it has the old server's name which I wanted, but I am stuck and can't get AD up).
The DNS server has the ED01 name. When I go to AD and 'Change Directory Server', Change to: This Domain Controller and type in the current name of the new server, its status is Online, but when I select it and click OK, I get the error above.
