  • DNS not resolving for non-clients

    I have a network with 2 servers (sbs2003 and 2003) and 2 subnets. the servers are configured with DNS servers.

    when I make nslookup non-domain-computer I receive the following answer:
    *** dns-server1.domain.local can't find non-domain-computer: Non-existent domain

    when I make nslookup domain-computer I receive the following answer:
    Name: domain-computer.domain.local
    Address: 192.168.0.26

    When I look at the PTR

    1) I cant resolve dns for non clients computers
    2) I can see these PTR records inside the DNS server
    3) Normally I had the answer for secondary dns server, but now I have only for the primary

    In one of my subnets the dhcp is configured with the option 015 and in the second subnet not, so this is not the problem.

    What can I do ?

    Re: DNS not resolving for non-clients

    So to clarify, DHCP is assigning addresses to non domain-joined computers, but is not updating DNS? Is DHCP configured to update DNS, and is DNS configured to accept nonsecure udpates?

        As in my last post: Is DHCP configured to update DNS, and is DNS configured to accept nonsecure udpates?

        If not, then there's your problem.

          No, the DNS is being updated but is not resolving the queries.

          I can find in the DNS PTRs the name of the non-client computers with the IP, but when I try to ping I receive this msg:

          *** dns1.server.domain.local can't find computername: Non-existent domain

            Do you see A records for them too?

              A couple of things to try:
              1. Configure primary dns suffix in System control panel, Computer Name, Change, More on client PC. Then reboot
              2. Ensure PC's TCPIP properties have their first DNS IP address pointing to your DNS server.
              3. Try some tests using NSLOOKUP

                I try to add the suffix but nothing. I have the msg, non-existent domain .

                Yes, the first DNS is my DNS server.

                I can see the records in the DNS console, but is not resolving the queries.

                  As per my question - do you see A records in the forward lookup zone, or can you only see PTR records in the reverse lookup zone.

                    Can you run an "IPCONFIG /ALL" from a CMD session and post the results for all concerned servers/workstations?

                        Ensure that in the TCP/IP settings on the clients you have enabled the option "Register this connection in DNS" or words to that effect.

                              As far as I know, you don't. It's the default behaviour on Windows machines. Check that it hasn't been disabled.
