ICS provides networked computers with the ability to share a single connection to the Internet.
If you have multiple computers, you can use ICS to allow you and others on your local area network (LAN) to perform different tasks simultaneously. For example, one person can send and receive e-mail messages, while another person downloads a file, and another person browses the Internet. You can also gain access to your corporate e-mail accounts from a client computer while others on your LAN cannot. You can use Web-enabled programs (such as downloading updates) as well as Microsoft NetMeeting and other video conferencing programs.
Internet Connection Sharing Capabilities
Windows Support for Connection SharingTo connect multiple computers to the Internet through a single Internet connection, one computer must be running Windows 98 Second Edition, Windows 2000, or Windows Millennium Edition (Me) with Internet Connection Sharing installed. Other computers on your LAN can then gain access to the Internet through the connection on the computer with Internet Connection Sharing.
NOTE: ICS is a built-in feature of Windows 98 Second Edition, Windows 2000, and Windows Me, and is not a component available for download.
