I've got a Windows 7 Home Premium 64-bit edition laptop trying to connect via VPN to a Windows Server 2003 and am getting the VPN Error 800. I set this connection up for the user while he was at a temporary location and it was working fine. When the user returned to his home, the connection no longer worked. Here are the troubleshooting steps I've done so far.
I am able to ping the VPN IP address from the laptop with no problems.
I have setup a second VPN connection to another server from the laptop and was able to connect. This second server was SBS 2008.
I have setup the VPN connection on my computer with that user's credentials and am able to connect without a problem.
I followed the troubleshooting steps in the link below and that didn't help.
I have restarted the server & laptop.
I have tried to configure a second VPN username and password from the same Server 2003 on the laptop and was not able to connect.
I would love some insight. Thanks.
