1 Server, 2 Independent Networks

I have 1 Win 2K3 Server with 2 Nics.

1. 192.168.1.10 255.255.255.0

2. 182.168.2.10 255.255.255.0 GW:192.168.2.1

Logged onto the server I can see both networks. I can get to the Internet on the 2 network with no problems.

Problem is PC’s on the 2 network can see the server but PC’s on the 1 network cannot.

If I set a GW on the 1 network as well, then it stops allowing me to get to the internet from the server.

What have I done wrong? Both networks are independent but both need access to the server.

I have an Ubuntu machine setup this way and it seems to work beautifully.

Thanks for the help,
Mike
