Internet connection sharing W2K Prof.

I have a home network consisting of an 8-port Ethernet hub with 3 Windows 2000 Prof. pc’s connected & 1 Win ME pc. I hope to soon have a network printer as well. I also have a cable modem connection via the uplink port on the hub.

I wish to shareout my internet connection to all the pc’s, & have been told the only way to do this (without additional hardware eg routers or additional network cards) is to configure the one machine that can access the internet as a Windows 2000 server.

How do I do this? What do I need to do to accomplish his?
