I have two completely separate networks, each running Windows 2000 server with XP workstations. Each has a router connecting to cable modems for internet connection. They are two separate businesses and would like drop the 2 cable connections for internet and split a T1 connection, for various reasons. I would like to know how to handle the sharing of the internet. I am not real familiar with working with subnets and such. I want to keep the networks as they are as far as domain names and IP ranges and all that. Assume one network has an IP range of 192.168.5.x and the other had 100.100.10.x could the servers for each domain point the workstations to a single router or what?
