I have a 2008 server that has already joined the domain. I've added the DNS server role and it has synched the zones with the 2003 DNS Server which is also the original active directory server.
On the 2003 i ran adprep32 /forestprep successfully.
Through changing my NIC DNS entry to the 2008 IP i have verified that i can connect to the domain.
i'm confused over a couple of technet articles as to how to proceed to give the 2008 control of the domain.
there's this article: http://support.microsoft.com/kb/255690
and there's this one: https://technet.microsoft.com/en-us/library/cc755937%28v=ws.10%29.aspx
my goal is to have the 2008 be the new DNS server and primary active directory eventually shutting off the 2003 machine. thanks!
