PPTP is most commonly used for enabling secure and encrypted communications to private enterprise networks via the Internet. In this scenario, the PPTP client must have two phonebook entries: one to connect to the Internet via an ISP and one to connect to a PPTP server on the target network.
However, if you are using PPTP to connect to a PPTP tunnel server on your LAN, you only need to have one phonebook entry: the PPTP server phonebook entry.
The following procedures describe how to use Dial-Up Networking to create phonebook entries for the ISP and the PPTP server.
