DFS server in Parent Domain is slow when there is no local DC

    Question

  • We are implementing DFS 2k8 R2 and have this set up in the Parent Domain where all of the DC's are 2k8 R2. We have "hub" dfs servers in strategic locations where we also have a parent domain DC/GC/DNS server. However at some of the satalite offices we only have child domain DC/GC's and we have been experiencing some latency when users attempt to access files/folders. Is this because it is contacting the parent domain DC over the WAN? Is there anything that we can do to direct it to a local DC/GC or will we be forced to install a parent Domain DC/GC at every site?  Any help would be appreciated

  • You could deploy RODC to your branches so that authentication and access to the file server could be made even if the WAN fails. You should properly configure sites and replication costs. Assign the correct DC to that site and the users will use that DC assignet to their site for authentication.

  • Hi,

    One hint: check your sites topology. DFS Namespaces are site-aware. On your specific case, do the following checks:

    • In the published folder targets, check the Exclude Targets outside of the client's site, this will force DFS not to accept folder targets outside the satelite location site. Important: you must define a specific site for each different network segment (remote location) and put the DFS server inside this specific site

    • Other way is to define priorities between the targets, this is in the Folder Target Properties. Here you can override the priority for the targets, giving a TOP prio for the local DFS server.

    In my opinion these 2 options can solve or reduce your problems.
