FQDN and DFS-R Namespace Referral

Discussion in 'Active Directory' started by Mark Rosenecker, Aug 22, 2007.

  1. I have a Windows Server 2003 R2-based DFS-R Namespace, which has three
    namespace servers associated with it. When adding a namespace server
    to the namespace, even if I specify a FQDN as the server name, once it
    is added, it appears only as the CN.

    That is, if I have a DFS-R Namespace of


    The Namespace servers appear as


    I would like them to appear as


    The reason for this is simple. When users in a trusted domain attempt
    to access that DFS-R namespace, they can't resolve the NetBIOS name (\
    \server1) without manually adding a DNS suffix to their search order
    in their IP configuration. I would rather have the namespace refer to
    the FQDN of the server, so that I don't have to reconfigure 2000 user
    PCs across the globe.

  3. Thank you Matthieu, but the article you referenced is for DFS, not the newer
    DFS-R in R2 of Windows Server 2003. DFS is the old version included with

    Anyone else? :)

  4. oups sorry...

    One workaround:
    add the hostname in the other domain's dns. So you won't have to change
    workstation config !

    I can't find more resource. Did you try the registry entry anyway ? It
    should be set before building the namespace.

  5. this works on my R2.

    Adding the key (in the dfs service) make the referral FQDN !
    Without this key, i agree, after refreshing the interface it convert to
    netbios name.

  6. Unfortunately adding the hostname into DNS won't work in all scenarios, as
    several of the domains in question we don't have direct control of. The best
    solution is to just have DFS-R link to the FQDN.

    I didn't try to change the DFS registry key, as I figured it wouldn't do a
    bit of good. Plus, I'd have to change it on two domain controllers, which I
    figured might be a bad idea.

  7. not quite accurate....

    DFS is just DFS namespaces. In W2K/W2K3 it automatically uses NTFRS as the
    replication mechanism. Those are two separate things.

    It becomes more clear in w2k3r2 as you talk about DFS namespaces and DFS
    replication mechanism (NTFRS or DFS-R). DFS-R is of course preferred

    DFS by default uses NetBIOS names for referrals and the info in the KB
    should help you chnage that behavior to DNS referrals
