I am setting up my first domain and I am going to park the name for a while and run the .com locally until I can figure out what I need to put it on the WAN. When I set up the first server as the domain controller how do I handle the IP setting for staying local and handling the local LAN? Do I have to give it and IP address of lets say 192.168.50.254 and in the Primary DNS point it at itself 127.0.0.1 so that it sees the .com? Also I have read that there should be 2 domain controllers in the domain- why?
All knowledge welcome.
