Recursive query fails

    Running Windows 2000 SP4 server

    I have a server with 2 NIC's. One internal, one external. When I go to DNS
    properties, interfaces tab and select the internal interface, recursive query
    tests pass. When I select the external, they fail. Anyone know why this is
    the case? I'd really like this server to only listen on the external
    interface. If I run an nslookup they also fail on the external interface.

    Thanks!

  2. Read inline please.

    In
    I'm not sure why the test fails, I haven't been able to reproduce the
    behavior on my Win2k DNS. That said, can I ask why you require your machine
    to listen only on the external Interface?
    DNS should listen only on the internal Interface, especially if it is a
    Domain Controller. DNS will create an A record for the machine name for all
    IP Addresses listened on, if it listens on the External Interface it becomes
    a problem because File Sharing should only be bound to the internal
    interface, this will cause Userenv errors and problem accessing Group
    Policies.
    If you need access from the External Interface, I recommend using NAT in
    RRAS to map 53 TCP and UDP to the internal interface IP.
