I am developing an intranet.  Is it possible for other people in different cities in the world but with rights to the intranet web server and accounts on my domain server to access the intranet using the Point-To-Point Tunneling protocol?

It all depends if you are on a private net. If you are, no one will be able to access the intranet. However, the point to point tunneling protocol is for your own intranets security and is just encrypting the port communication between your host and the other connection.

I used the articles above with some success.  These two helped me the most.  They cover the topic in a little more depth and give you pointers for things like adding routes to remote subnets behind the VPN.

Pitfalls...

An ISP who filters GRE protocol 47

Server not dedicated to being a VPN server (I have an SBS server that acts as an email server and the VPN server - so I can't enable PPTP filtering to lock down access)

If you do have a dual function server, try using Advanced TCP/IP security instead of PPTP filtering to protect the other incoming ports on your server - but don't be suprised if it does not work.  I wound up unbinding the server, workstation, and NetBIOS services from my server's public NIC.)

There are patches to patch the patches on the client side and server side!!!  Make sure you are on the latest service pack for NT.
