    Nslookup Domain Controller

    When i try nslookup from my domain (either from domaincontrolle r or from any client) it says

    C:\Users\usaf.E ITS>nslookup
    Default Server: UnKnown
    Address: 192.168.0.100:5 3



    why UNKNOWN ?

      DNS is resolving queries, but why its showing unknown ?

      like

      C:\Users\usaf.E ITS>nslookup
      Default Server: UnKnown
      Address: 192.168.0.100:5 3

        Double check your ip settings, your DNS should be pointing to your domain server (controller)

        so lets see that full address of yours go to start>run>cmd hit OK and type in ipconfig /all

        get the address and get back to us.

            May I suggest

            Your Default Gateway and DHCP server should be your router (192.168.0.1)

            Your DNS and WINS Server should be your server (192.168.0.100)

            The DNS addresses 212.158.192.3
            212.158.192.2 should not be showing up, in other words take them out of the router configuration, the only DNS address on the router should be 192.168.0.100

            The 212.158.192.3
            212.158.192.2 should be configured on the server side only as forward.


            Let me know if you need help on setting this up. This is the way I have my $4000 Sonicwall Configured =) and it works flawless on the network.
            Now I assume you have a static IP address from your ISP for this to work.

            Let me know what you think, Cyber.

              i can change the dhcp from windows server to cisco router, but what i'm afraid of if all the other staff's computers get different ip (192.168.x.x) will create problem for me, kaz their ips are translated out to specific external ips.



              or they will given same ips as given by windows server ? Windows dhcp is not configured to give them static ips using mac address, but still if they even reboot their machines ,are getting the same ips.

              will you suggest that b4 swaping to cisco from windows dhcp, i should do mac address entries to get the same ips as they are currently on: ?

                Absolutely, there should be a list on hand where you have all the mac addresses and ip addresses on hand so that you can configure it all right. On a weekend when nobody is at work Set all pcs to get DHCP and turn them off (except for the server of course) Configure your Cisco router and start bringing the pcs back up, verify that the settings work (you can browse the internet and the stations see the server). I would also suggest a backup of present settings on the Cisco side.

                Good Luck, Cyber.
