By creating an incoming connection, a computer can act as a remote access server if it is running Windows XP Professional, Windows 2000 Professional, or if it is a stand-alone computer running Windows 2000 Server. You can configure an incoming connection to accept the following connection types: dial-up (modem, ISDN, X.25), virtual private network (VPN) (PPTP, L2TP), or direct (serial, infrared). On a computer running Windows 2000 Professional or Windows XP Professional, an incoming connection can accept up to three incoming calls, up to one of each of these types. On a computer running Windows 2000 Server or Whistler , the number of inbound calls is only limited by the computer and its hardware configuration. For information about earlier versions of Windows NT Server (and other operating systems) that can connect to an incoming connection, see Incoming connection clients
You can use the Mulitlink feature to configure multiple modems or ISDN adapters for use with incoming dial-up connections. For more information on Multilink, see Configuring multiple device dialing
When you create a connection, the users that can connect to your incoming connection and their network protocols are selected. Each user that connects to an incoming connection must have established a local user account. For more information about user settings such as name, password, and callback rights, see To grant incoming connection access rights to your computer For more information about configuring your connection for the TCP/IP network protocol, see To configure an incoming connection to use TCP/IP For more information about configuring your connection for the IPX network protocol, see To configure an incoming connection to use IPX The IPX/SPX protocol is not available on Windows XP 64-Bit Edition.
