The Draft Defines the following

   Network Access Server (NAS)

      A device providing temporary, on-demand network access to users.
      This access is point-to-point using PSTN or ISDN lines.

   PPTP Access Concentrator (PAC)

      A device attached to one or more PSTN or ISDN lines capable of PPP
      operation and of handling the PPTP protocol. The PAC need only
      implement TCP/IP to pass traffic to one or more PNSs. It may also
      tunnel non-IP protocols.

   PPTP Network Server (PNS)

      A PNS is envisioned to operate on general-purpose computing/server
      platforms. The PNS handles the server side of the PPTP protocol.
      Since PPTP relies completely on TCP/IP and is independent of the
      interface hardware, the PNS may use any combination of IP
      interface hardware including LAN and WAN devices.

The PPTP Server is Clearly the PNS and NOT the PAC
