Configure network adapter

    Question

  • Hello forum.

    My server is connected to another server.

    I therefore have 2 network cards.

    The local area connection 2 that is reciving dhcp and dns from the other server is set up like this.

    10.0.0.178

    255.255.255.0

    10.100.17.254

    dns: 10.100.97.19

    (The server has internet access)

     

    The other network card that is deploying dhcp to my clients is set up like this:

    192.168.1.1

    255.255.255.0

    dns: 10.100.97.19

    The clients get dhcp and that is working fine, but the

    clients get no internet access.

    In the event viewer on the dns it stands that i have to add a loopback address.

     

    What have i configured wrong?

  • Appears router is providing DHCP? I'd lose one of the NIC on server. Basically your DHCP server (router in your case)must hand out static address of AD server as primary DNS server address so clients can find DC. Then put the ISP's DNS addresses in the forward lookup of your DNS server so clients can find internet. Also make sure your server  has static IP address outside of DHCP

    Trying to route through server is going to de difficult and cause you much greif.

  • We need to have 2 nics on the server.

    In our network we will have 2 dhcp servers but only one of those server will provide the DNS.

     

    How to configure?

  • The server that is handing out ip-addresses to my clients have those roles.

     

    My server is getting dns and dhcp from another server in the network
