Hi I have a few pcs that need to connect to two different networks. I assume that I will need two nic cards with ip addresses on both networks, I'm just not sure how the configuration should be setup to have the cards communicate. Looking for a document or help on this. Thanks. PCs running w2k and XP

I know you can do this in windows server 2003, and I *think* you can do it in XP.

If you go into the properties of the connection, and then the properties of the TCP/IP protocol, set up the IP, Subnet Mask, Gateway, and DNS server to be on one of the networks. Then, click Advanced, and under the first tab, where it says IP addresses, you can add more. If you add an IP and subnet mask that is in the second network on every client, you *should* be able to use it on both networks. It's sort of like a virtual NIC. Note that this only works if there are two networks, and they are on the same PHYSICAL network (like both connected to the same switch)

Otherwise, you could put a router between the two networks. The router would need to have a physical connection to each network. Then, if you set it as the default gateway for both networks, it would just pass anything that was supposed to cross over into the other one to the correct side. If you then set the default gateway of the ROUTER (not any of the PC's, but the actual router's IP configuration) to that of your firewall/modem/whatever you use, they could both access the internet too.

And yes, your other suggestion would also work, with two NIC cards in each computer, but that's gets a little expensive.

Hello,


It's going to depend on these networks. Are they completely separated? You should be able to do this without adding separate network cards in your PC's. It's going to depends on what type of network gear you have besides your PC'S / Servers. This can be done with switches and routes.
