This appears to already be partially covered in other questions but I want to make sure all goes well. I just successfully added a second DC that I intend to become the master and retired the DC/DNS server. I keep seeing mention of DNS intergrated AD and I am confused since my new DC does not appear to have DNS installed but I can see AD objects. Should I have installed DNS first? How do I make my new DC the DNS server? Should it become a global catalog first? Thanks.
