I have 3 locations and have setup additional domain controllers at the remote sites to keep some of the traffic to a minimum over the WAN link. I have followed the instructions on my previous post http://www.experts-exchange.com/Operating_Systems/Windows_Server_2003/Q_21828243.html
but still a little confused on how the DNS works. I have promoted the new server in the subnet of the remote location and setup the new site in Sites and Services. Will all authentication now occur locally on that subnet? I also installed DNS on the new server but didnt know if I needed to setup a new Forward Lookup Zone or replicate from the domain controller at the other site? Is there a setting I need to change on the DNS server at the main site? Please help.
