I have a multihomed (two NICs) system WinNT4 SP6 that I am trying to configure with two different distinct simultaneous DSL lines and two routers. The first is a gigabit NIC that works just fine through DSL Router1 (not DHCP capable) on IP xxx.xxx.xxx.xxx to the first DSL connection. The second is a 100megabit NIC that I can not seem to configure to use the DHCP server in Router2 (DHCP enabled) on IP yyy.yyy.yyy.yyy. When I go into Control Panel / Network / TCPIP Propeties and choose the second NIC (100MB) it properly shows "Obtain IP address from a DHCP server". However, when I click on the Advanced button, and choose the second NIC, even though it shows "DHCP Enabled" for the IP address, the gateway shows xxx.xxx.xxx.xxx, which is the address of Router1! When I remove or change this address to yyy.yyy.yyy.yyy which is the IP address of Router2 configured as the DHCP server, WinNT changes it back automatically to xxx.xxx.xxx.xxx even after rebooting! How can I have two NICs each pointing to its own router? I appreciate any help you can give me. I do not have the option of disabling the gigabit NIC as we need it.
