I have a 2008 Server that is going to hold Active Directory and Exchange that will be in a Colo. I am then going to have two other locations with an 2008 Server at each. The second and third location will connect to the Colo via a VPN. The Second and third location will connect to each other via a 3mb MPLS line. I want to setup DFS on all three to keep a copy of the data which is mostly AutoCad files and some Office documents, on all three servers. This way if the connection between them is broken they will still be able to login and access documents. I am not sure how to add the 2nd and 3rd location to the Server in the Colo though. I am not 100% sure that what I am proposing will work either.
