Setup DHCP with backchannel NIC

March 15, 2009 at 12:14:05
Specs: Windows Server 2003
I am trying to setup a Windows 2003 box with a backchannel NIC for internet. I have a second NIC on this box on a private network that I would like to enable DHCP on. I have the service installed, but DHCP is only seeing the backchannel NIC. I don't want IPs to be handed out on that network, only on the 2nd NIC's network. The DHCP scope wizard doesn't give any options to specifically allocate a NIC to DHCP. Any help with this issue would be greatly appreciated.

Thanks.

Dual NICs in Windows is a nightmare. What is your ultimate goal? You may not need two NICs to achieve it.

Essentially I'm just trying to create a DHCP for the private network and still get updates for Windows 2k3 and download software I need on the server. I may also want to use the server as a gateway for the internet eventually, but I won't now if it complicates things too much. The main reason I gave the machine two NICs was a protection measure on the established backchannel network which has IPs being handed out already from another DHCP. I'd be happy to answer any more questions about the setup if it helps. Thanks so much for the reply.

That's not going to work with 2 DHCP server running. You can try static IP addresses and maybe add a route table it needed but your router should be your gateway, not your server.
