    Maybe I am missing something here.
    My setup:
    server1 (original DC that DFS was setup on)
    server2 (nas box)
    server3 (just added dc to decommission server1)

    remote_server4 (remote dc over t1)

    the root is replicated to all servers, yet when I take server1 offline. I
    can no longer see my root is the mmc on any server. I try to connect to it,
    no good.
    DFS can still be access by clients when this is happing.
    When I bring up server1 again, I can get back to my root.
    Anybody see this?
    Thanks in advance!!

  3. You might want to have a look at the DFS FAQ on
    http://www.microsoft.com/dfs. There is the following there (among
    other things).

    Use the following procedure to decommission a root server:

    Remove the root server from the DFS namespace by using one of the
    following methods:

    • In the Distributed File System snap-in, right-click the root target
    you want to remove, and then click Remove Target.

    • Using the version of Dfsutil.exe included in the Windows Server 2003
    Support Tools, run the following command, where RootTargetServer
    refers to the root server to be decommissioned:

    Dfsutil /UnmapFtRoot /Root:<DFSName> /Server:RootTargetServer

    On the decommissioned root target, remove DFS information from the
    registry by using the following Dfsutil.exe command:
    Dfsutil /Clean /Server:RootTargetServer /Share:<RootName>

    On the decommissioned root target, at the command prompt, type net
    stop dfs & net start dfs.

    After you remove a root target, DFS stops giving referrals to the
    decommissioned server within 15 minutes of the update to the DFS
    Active Directory object on the local domain controller from the PDC
    emulator master. (This update can take time depending on Active
    Directory replication schedules.)

    Note I'm not a DFS expert.


    Please post FRS related questions to
    microsoft.public.windows.server.dfs_frs and prefix the subject line
    with "FRS:" to make it easier to spot. Note that FRS is used to
    replicate SYSVOL on domain controllers and DFS root and link targets.
