You need to assign your server a static address. If the router is you can give the server (if no other device is using this address) with the subnet usually being and gateway being Also install active directory and DNS. In your network card configuration the DNS should be which is the server itself. Also on the DNS forwarding tab, you can put your ISP DNS servers.

Next configure your DHCP with the ip range you want…Say to So anything with back would be static and be excluded in your DHCP scope. Go to DHCP scope options and check that the Gateway is configured with, DNS address is and with the correct domain name.

I think that you need two NIC cards to enable DHCP on the Windows Server when it is disabled in the network router. One NIC to the router out to the internet, and the second to a switch for the LAN.

I would use only one network card. Why do you need 2 routers? Are both routers on the same subnet? Also, just leave the alternate DNS blank. Do an ipconfig/all and post the results. Can you describe exactly how you connected these devices?
