So within that past month my mobile users have started having issues with our VPN. One day they can connect with no problems and then the next day they receive error 800 or error 807. There are several weird things going on. For one it doesn't just happen to certain users. The problem effects one user one day and then another user the next day. Also some can connect while others cannot. And in one case we had two users co-located at the same offsite place and neither could connect. One had error 800 and the other had 807. Also, the users can ping the vpn server but as soon as they receive the error 800 or 807 they can no longer ping it. I tried restarting the vpn server for a user that received one of those errrors and could no longer ping the server. Once the server rebooted the user was able to ping but when he tried to connect he got the error and then was no longer able to ping it. Does anyone have any ideas for me? The vpn server is on Server 2008 and my clients run Windows 7.
