  • Can't figure out why NSLOOKUP Fails

    I'm a MCSE (NT 4) with a MSDST certificate who is looking to get certified on 2003 Server. In my current job I do not have any networking responsibilities so my knowledge has faded.

    I have a 2003 Server R2 Eval running on a Dell SC420 PC.

    I have run DCPROMO and let it create a domain named levy.home

    I've used the DNS Admin tool to populate the domain with A records for the server. If I have the DNS Server set to 127.0.0.1 I am able to look up any machine on the local network. If I change it to 192.168.3.3 which is the IP of the server nslookup fails.

    C:\WINDOWS>nslookup
    *** Can't find server name for address 192.168.3.3: Non-existent domain
    Default Server: UnKnown
    Address: 192.168.3.3

    In Event viewer there are no DNS errors.

    What have I possibly overlooked? Once I can get the server to successfully use itself for DNS lookups the computers I have with XP Pro should be able to joinnth domain.

    It sounds like you are missing the reverse lookup zone for the 192.168.3.x subnet.

      I do have a reverse lookup zone defined.

      I've also included screen shots of DNS management

        Is the server configured to use itself for DNS?

          I believe it is.

            And when the DNS server is set to listen on 192.168.3.3 nslookup fails?

              I was all set to say correct nslookup fails but I tested it again (and I swear that I made no changes) now it's working.

              I'm going to reboot and see if it's still working.
