"Decide whether to allow client computers to control the server's Internet connection using the Internet Gateway. This feature is automatically available on clients running Windows XP. On clients running Windows 98, Windows 98 Second Edition, or Windows Me, you must run XP's Network Setup Wizard to enable the gateway. If you have a Windows XP CD-ROM, you can run the Wizard from it. Otherwise, create a network setup disk containing the Wizard files."
