We have a SBS2k3 domain at the main business office and a branch office that connects thru a VPN to the domain. Ever since it was installed (not by me), there is a tremendous delay when users at the branch office login and sometimes the shared resources are unreachable. My thought was to put a SBS machine at the branch office to handle local logins and to store a replication of the main office data for faster access. I am a bit new to the AD world.....I am more used to PDC/BDC relationships. From what I have read, there really isn't a strict PDC/BDC in AD so I am not sure how to make this work...or even if it will solve the problem. Does it seem like it should fix the lag in the VPN to have the branch users login to a local server? Any help would be much appreciated!
