Error NetBT ID 4321 on a Windows 2003 Server R2 member server

    Question

  • Hi all,

    I've an AD domain with 2 Windows 2000 Server and 1 Windows 2003 R2 domain controllers. I've added a member server a Windows 2003 R2 Server. Suddenly in the eventlog of this last machine I get error NetBT 4321 every few minutes:

    The name "TRUST          :1d" could not be registered on the Interface with IP address 192.168.0.115. The machine with the IP address 192.168.0.62 did not allow the name to be claimed by this machine.

    Where "TRUST" is the NetBios name of my ad domain

    192.168.0.115 is the server I've added

    192.168.0.62 is the Windows 2003 Controller

  • Hello,

    let's start with an unedited ipconfig /all from all DC/DNS servers of the domain.

  • Hello,

    first serpro01 is multihomed and RRAS is enabled, which is NOT recommended on DCs and result in multiple problems as you see.

    Also  serpro02 use 2 ip addresses.

    In your case remove RRAS from the first DC and also the second ip address form the other server. Then run ipconfig /flushdns and ipconfig /registerdns and restart the netlogon service on them. Do not forget to control the DNS zones for incorrect DNS records.

  • I've inherited the two multihomed RRAS enabled DCs and by now, I can't touch them. But why Have I the NetBT error on only one server? And not an all member servers? I agree that multihomed RRAS enabled Dcs aren't the best (and I've planned to change this) but I'm not sure that the NetBT error is dependant on this.

  • Hello,

    "The name "TRUST :1d" could not be registered on the Interface with IP address 192.168.0.115. The machine with the IP address 192.168.0.62 did not allow the name to be claimed by this machine"

    This belongs to the multiple and different ip addresses on each DNS server which also try to register in DNS.
