The following (5 secs KB search) sounds like it (or check KB Q161986):

Microsoft Knowledge Base

PPTP Connection to Multihomed Server May Not Succeed

Last reviewed: July 23, 1997
Article ID: Q169843 The information in this article applies to:

•Microsoft Windows NT Workstation version 4.0 •Microsoft Windows NT Server version 4.0







SYMPTOMS

When you use Dial-Up Networking to connect to your Internet service provider (ISP), and then attempt to make a PPTP connection to a remote LAN, you may receive the following error message:



   Error 629: The port was disconnected by the remote machine.






CAUSE

Default gateways are configured for each of the network adapters in the multihomed PPTP server.





RESOLUTION

Configure a default gateway on only one network adapter in the PPTP server. Only one default gateway should be configured on any multihomed computer.

Comment:  There is one network adapter in the PPTP server in the installation I'm doing and I'm having same results.
Is there a port number that has to be open in the router's firewall?  What does "multihomed" computer mean in this case? see answer from "kuk".

rcaro: PPTP needs the GRE protocol (number 47) and port 1723 - see KB Q162847. However, failure in this area should yield messages "No Answer" or "Error 650 Server not responding". Multihomed= more that 1 network interface with tcp/ip bound.
