I have a Windows 2003 server as DC and two App Servers running W2003 Server. One of them is acting as a backup domain controller. I want to disjoin the backup DC from the old Domain and join the new domain.
However when I open My Computer Properties to disjoin the server, I get the message seen in attached.
I understand that I need to demote this server so that it does not act like a backup domain controller.
However I wanted to following steps given by experts so that I don't screw up things on this app server.
There are two application software that users depend on from this server, so I need to be careful.
Client programs on workstations access the data on this server by NETBIOS Computer name or IP address, so I think it would be alright to move this computer from old domain to the new domain as long as there is no change in IP address or computer name.
