Windows – Why doesn’t the PPTP VPN connection stay alive with RDP on WM6.1

pptproutervpnwindows-mobile

I have my Windows Mobile 6.1 Device connecting to my home router via PPTP VPN. I am able to RDP into a machine at home and see the screen. This will last for no more than a minute. The VPN connection will drop for no apparent reason.

Connecting to the RDP session via wifi @home works fine and never disconnects. Connecting via VPN and RDP from a regular windows machine is fine. It is something Windows Mobile and VPN related.

How can I keep my VPN connection alive when using Windows Mobile?

Best Answer

It could be a keepalive issue.

RDP doesn't send traffic unless it has to, and it could be that your connection thinks nothing is happening and closing.

On the RDP server (assumes server 2003):

  1. Click Start, click Run, type gpedit.msc, and then click OK.
  2. Expand Computer Configuration, expand Administrative Templates, expand Windows Components, and then click Terminal Services.
  3. In the right pane, double-click Keep-Alive Connections.
  4. Click Enabled, and then click OK.
  5. Close Group Policy Object Editor, click OK, and then quit Active Directory Users and Computers.
