I currently have a 2003 network, with two AD servers (A & B). I in the process of retiring A, and have a new 2008 R2 server to go in its place. Server A is also currently a DNS server (and it was the first one implemented).
I have done the ADPrep work to make the forest/domain ready for the new 2008 server. I want this server to do two things on my network:
1) An AD controller
2) the main DNS server on the network.
I want to confirm the best way to install these roles on the new 2008 machine. Should I install DNS first, and then install AD? What about DNS-Aware AD? Does that fit in here anywhere? Anything else?
