You need to assign your server a static address. If the router is 192.168.1.1 you can give the server 192.168.1.2 (if no other device is using this address) with the subnet usually being 255.255.255.0 and gateway being 192.168.1.1. Also install active directory and DNS. In your network card configuration the DNS should be 192.168.1.2 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 192.168.1.10 to 192.168.1.100. So anything with 192.168.1.9 back would be static and be excluded in your DHCP scope. Go to DHCP scope options and check that the Gateway is configured with 192.168.1.1, DNS address is 192.168.1.2 and with the correct...

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?
