Windows 7: Dual NIC, 2 Segment configuration question

Dual NIC, 2 Segment configuration question

I have a dual NIC in my work desktop (Windows 7 Ultimate 64 bit) connecting to separate routers. Eeach router has internet access, each on a different segment, each on the same subnet. We have 2 independent networks here. One segment is a domain and the other is a work group. Both have multiple servers.

The first NIC's IPv4 is configured with a static IP Address on a Domain and has a gateway configured. The second one also has a static IP address in a work group and is configured with no gateway. This seems to work fine, but the second one shows up as a Public newtork and I would prefer it to be a Work network.

Researching this pointed me to an article that said networks without default gateways are always public.

I changed the second NIC to also have a default gateway, matching the router's IP Address on the second segment. Windows slapped me for having 2 default gatewyas and let me save it anyway. Now, both connections are showing up under Domain Network and everything seems to be working fine. Both connections show that they have internet connectivity.

I fear that just because they seem to be working does not necessarily mean that is is working efficiently. I am also not positive that it even matters that the second one is listed as a Public network. Can anyone identify the proper configuration in my situation?

OK, after a bit more poking I now have the second router configured to assign a static leased IP Address for my second NIC where it assigns the NIC an IP address based on the MAC Address of the card. Then I configured the ipv4 for that card to obtain an ip address automatically.

Now, that connection's details show the original IP Address (the one I had previously set as a static IP on the card itself) as well as a default gateway (Router #2's IP Address), and I am no longer getting slapped by Windows for having 2 default gateways (even though each connection shows that it has a default gateway in the details). It is also showing up as a connection in the Domain Network's location.

Visually, this seems to be set up the way I would expect to have it, but I am still not 100% positive that I have good expectations.

Any input?
