Namespace Servers

    Without replicating data to & from file servers in separate sites, how can I
    replicate the DFS namespace between the sites? The goal is to maintain a
    namespace server in either site when the site connection goes down. Does
    this mean that a second namespace server should be created in the site that
    currently does not have one? A domain-based DFS I thought would have taken
    care of this situation.

    All systems Win2003 R2 SP2 (with at least one DC in each).

    Create a second root target for your domain-based DFS structure pointing to
    a share on the server in the second site. This will alow you to access the
    root of the DFS namespace (and, potentially, traverse it down the DFS
    hierarchy) even if the connection between the sites is severed (taking
    advantage of the local domain controller). However, I'm not really clear to
    what extent this would be beneficial, since you seem to indicate that you
    maintain only a single copy of your data (which would cease to be accessible
    once the connection to the first site is no longer available).

    JK,

    I think we need a list of your Server's and their roles.

    If the current server hosting the root and the files is the only one
    available, if this goes down you lose access to the files as well, even if
    there is another copy of the DFS root information available.

    The way I have my server's setup, which is a tad overkill but I have my
    reasons, is the following.

    Catalogue - Hosting DFS-Roots (VLAN1)
    Store1 - First copy of the file shares (VLAN1)
    Store2 - Second copy of the file shares on seperate subnet (VLAN2)

    So if a file store server went down, there is another copy available. I
    setup my DFS this way because I can isolate the roots from the file store
    servers and keep it managable. However if your roots and file shares are on
    one server, and thats your only copy of the files, you lose roots and file
    shares in one go, even if you have seperate root replica servers holding the
    namespace afloat.

    I'm sure this is probably more suitable to me than pretty much anybody else
    but it works great and I feel happy having two copies of data on my network
    identical and ready to fail over in the event of losing a store.
