I used this article to allow my Windows 2003 Server to also be a PPTP server. However, after I do these steps users on the LAN cannot connect to the server anymore. I need LAN users to still be able to connect and I only have one interface. Adding a second interface is not an option. Can someone very experienced that has been able to solve this issue provide me the steps I need to do (or change) to allow both on the same interface?
