We are experience problems with our Microsoft SBS 2008 server, suddenly clients cannot connect through PPTP VPN, and we have tried anything, but nothing seems to be working (but it worked a month ago).
The error says:
Error 628: The Connection was terminated by the remote computer before it could be completed…
I found some additional information from activating logging from the client it receives the following error:
There could not be established connection on port VPN3-1. This is because the selected authentication protocol. Check if the operating system on the client and server support the selected authentication protocol(The message is translated from Danish).
I find it to hard track any error regarding this following problem from the EventViewer…
The VPN Is configured through the Windows SBS console. I have tried to reinstall the VPN connection, and restart have been performed. Windows firewall is off and i have tried to disable anitvirus..
