Hi, I am getting VPN Error 812: The connection was prevented because of a policy configured on your RAS/VPN server. Specifically the authentication method used by the server to verify your username and password may not match the authenictaion method configured in your connection profile. Please contact administrator of the RAS.. I am using MS CHAP V2 authentication both on server( Windows 2008 64 bit with TMG 2010) and client(Windows 7) system. Any suggestion? Sincerely Vineet
