I have a Windows Server 2003 PPTP VPN configured through RRAS. Windows XP and OSX clients connect perfectly fine, indicating the firewall is configured properly. No matter how I alter the authentication method on the Windows 7 native VPN client or RRAS VPN server side (to match), it always stalls at "Verifying Username and Password" and eventually spits out error 806. I am attempting to use MSCHAPv2, with it selected on both client and server side, to no avail. Can someone help?
