I am trying to connect with a VPN to ABC.com from Location A, and it connect successfully but after 3.5 minutes it disconnects (always 3.5 minutes give or take a few seconds), and then I have to wait a few minutes before I can connect again, but the it once again disconnects me after 3.5 minutes. From any other location I am able to stay connected for hours, and I am able to have things download and upload at Location A without using the VPN for hours. So, any ideas how I can make my VPN connection more stable at Location A?
Server is Windows 2003 Web Edition that is part of a domain, laptop runs Windows XP SP2 that is also part of that domain. I have also tried it from a PocketPC 2003 and a Windows 2000 SP4 machine that is not part of the domain, same effect. It is using a PPTP VPN and both the client and server are on private networks, the server has a ports mapped from the public IP address.
