Hello Under Windows 7 and Windows XP I have VPN with preshared key (remote server is Windows 2008 Standard) and all works fine. But when trying to configure IPSec with certificate i have 810 error code. There are certificates installed properly in my local storage (computer). I have one in storage computer in personal tab (mmc) and one in trusted root CA (computer and user). I don't know what I should looking for. Best Regards Przemysaw Staniszewski
