Hi, I have been trying to setup a VPN between a desktop and laptop that are both running windows 7 prof. The desktop is the server and laptop is the client. My laptop will go through the process of connecting after I file in the needed info (domain, user name, device name, etc). I am getting an error (error 720 a connection to the remote computer could not be established) after my laptop. I get the error message after it attempts to register on the network. Both of these computers are on the same network at the moment. The server is the target of the DMZ from my router. I have attempted to follow the insructions in the below link, but it appears to be more for XP then 7. http://social.technet.microsoft.com/Forums/en/w7itpronetworking/thread/eb37b71e-a021-47ee-896e-186cef55bf11
