I have an interesting problem regarding VPN connections (it happens when trying to connect either from XP client or Win7 client).
For example, user is able to connect to our VPN server normally and without any errors using home ADSL. Next day when it tries to connect using this same home ADSL line it gets "Error 806", but if he connects to the internet using wireless USB stick (T-Mobile in Croatia..) and then tries to connect to VPN, he can connect normally again..
This happens 2 or 3 times per week, but when it happens it's usually in the worst possible moment :)
Our configuration is :
- virtual Win Server 2008 R2 - RRAS installed
- we're using PPTP
- server is not behind any kind of firewall
Any kind of help or guidance would be much appreciated, since I'm stuck here :)
