  • Client on NetWork B can not ping Domain of network A

    here is the network :

    PCs A <---------> Domain Controller A (1st) <------------> Domain Controller B(2nd) <------------> PCs B

    IP address:
    -------192.168.1.0 ------------- ------------- 203.0.0.0 ------------------------------ 192.168.2.0


    the default gateway of PCs B is 192.168.2.2 ( IP of DC B) .
    But PCs B can not ping DC A using 203.0.0.2
    I can not understand . Anyone Help me, thank you very much.

    Could you provide a little more information on your setup?
    Are the DCs also running RRAS or do you have another device acting as the router?
    Are there any firewall?
    Can the DCs see each other?
    203.0.0.0 network is in the public range. Do you have control of this network?

      Thank you JeremyW for responding.
      This is just a LAB ( I am a Student only). So I config the IP Address 203.0.0.0 .
      DC B can Ping DC A,
      DC B is running RRAS as a DHCP relay Agent. And I am trying to use PCs B to obtain IP from DC A.

      Thank you.

        You need to check the routing on DC B. --> See Routing and Remote Access.

        Although I wouldn't recommend this for a live network, it is nice to kno how to do this with Windows.

          Marcel is right, the main issue is probably DC B is not configured as a router.
          You'll also want to make sure you have a proper scope setup on DC A for 192.168.2.0 network.
