We are in the process of planning a move of all of our servers from our in house server room to a Co-Lo data center hosting facility.
Right now, in our main site, we have two 2003 Domain Controllers and they are moving to the hosting facility.
Our main site will be connected to the Hosting Facility by very fast and redundant dark fiber and is supposed to act like a very long Ethernet cable. Our network IP addresses will not change.
There was talk about adding two new DCs in the main site to keep all of the authentication traffic local, but I don't think we'll be able to control that because the network IPs won't change, so I really don't have another Site to put DCs in.
Is there a point to having two domain controllers at the hosting facility and another two domain controllers at the main site?
Thanks for your input and thoughts.
