We are trying to upgrade an old windows 2003 server, We have installed a new server and have performed a DCPROMO. We have also moved all of the roles over to the new AD Server. However, when I shut off the old server I am unable to authenticate on the domain. There seems to be some dependency on the old server. Once its powered back on we can log in to the domain again.
New server is called Server01
Old server is called server1
domain is (example name) mydomain.com
workstations and other servers log on to the mydomain_nt domain...
