How do I set-up Internet Connection Sharing on Windows XP?

With Internet Connection Sharing, you can connect computers on your home or on your small office network to the Internet over a single connection. For example, if you turn on Internet Connection Sharing on a computer that connects to the Internet by using a dial-up connection or a Internet connection that requires your computer, other computers or devices on the network can connect to the Internet.

To use Internet Connection Sharing to share your Internet connection, the connecting computer must have one network adapter that is configured to connect to the internal network, and one network adapter or modem that is configured to connect to the Internet.
