  • NetBT - Error 4321

    Hi All,

    Currently have 3 Domain Controllers, 2x 2003, and one recently installed 2008 R2, several weeks ago)

    But I am getting some weird error, that I can't explain to myself.

    "The name "DOMAINNAME:1d" could not be registered on the interface with IP address xxx.xxx.xxx.27. THe computer with the IP address xxx.xxx.xxx.20 did not allow the name to be claimed by this computer"

    x.27 is the new 2008 DC,
    x.20 is the FSMO 2003 DC
    both on the same DOMAIN, in the same forest.

    So why is .27 trying to claim the name DOMAINNAME within the same domain?

    This error message happened 3 days ago and not had them since.

    Many thanks

    Have you got WINS configured on the NIC? or are you just using broadcasts for Netbios resolution?
    Networking connectivity or firewall related possibly??!

      No, got no WINS server, so yes Broadcasts...

      Hmmm I have used the 'security configuration wizard', which I did on 10th Feb 2012,
      but the first NetBT error appeared on the 23rd of Feb. But not any more errors since 24th...

      So maybe at the time there was some connectivity error.

      So this maybe not a major issue, but thanks anyway.
