Introduction 

PPTP  is  a  tunneling  protocol  defined  by  the  PPTP  forum  that  allows  PPP  packets  to  be  encapsulated  within 

Internet Protocol (IP) packets and forwarded over any IP network, including the Internet itself.   

In order to run the Windows 9x PPTP client, you must be able to establish an IP connection with a tunnel server 

such as the Windows NT Server 4.0 Remote Access Server.
