Window 8 workstations, but only periodically, and most frequently after a disconnect has occurred and the user is trying to reconnect to the VPN. Sometimes starting and stopping RRAS on the server will resolve the issue, sometimes rebooting the RRAS server will resolve it, and other times simply trying again an hour later will result in success. I windows 7 error 812 the connection was prevented because of a policy did some searching on the Internet, but virtually all of the resolutions for this issue are related to setup or configuration problems that would result in the VPN either consistently working or not-working for a specific workstation, not a random occurrence of this error. I tried changing a number of the NPS policies, since the error seemed to point to an NPS issue, but this did not resolve the problem. Eventually I was able to isolate the issue to a periodic problem with the RRAS server not being able to connect to the Active Directory server for account authentication. One of the reason codes occasionally generated in the security event log was: The Network Policy Server was unable to connect to a domain controller in the domain where the account is located.

Error 812 The Connection Was Prevented Windows 8
Greetings, I am trying to solve an issues with a clients new 2012 Essentials Server. the connection was prevented because of a policy configured on your ras/vpn windows 10 2012 Essentials Server VPN was working just fine the stopped and now having 812 error for remote client trying to VPN. RemoteWebAccess windows 10 vpn error 812 via browser to just look at files, etc works fine. Only VPN fails. Have ran a repair on the Remote Setup on Server with no change. Checked for updates and rebooted the server, no change. As all the http://roger.dilsner.com/random-vpn-error-812-solved/ setup is done via a Wizard, not sure what could be the issue. I have ran tracing and have captured logs if that would help. Friday, February 22, 2013 7:17 AM Reply | Quote All replies 0 Sign in to vote Have you rebooted the router? Have you checked the event logs of the server? Did you use UPnP on the router? Did the IP of the Essentials server change?Robert Pearman SBS MVP itauthority.co.uk | Title(Required) https://social.technet.microsoft.com/Forums/windows/en-US/f17ec934-821c-4fe7-bb44-679bdf0e4ad3/2012-essentials-vpn-error-812-rasvpn-authentication-method?forum=winserveressentials Facebook | Twitter | Linked in | Google+ Friday, February 22, 2013 9:20 AM Reply | Quote Moderator 0 Sign in to vote Router reboot - no I will look at the logs of the server but I did enable tracing and have that log on the client side if that would help UPnP no I don't believe so - it is a sonicwall device and I couldn't find that it was UPnP compatible, but this was working before for over 1 month IP was static and I don't believe it has changed but will check. I can use remote access wia web to upload download etc, just not full VPN. Thanks for the reply Friday, February 22, 2013 9:19 PM Reply | Quote 0 Sign in to vote Was the connection on the client configured by the connector software, or did you hand create it? The reason I ask, the SSTP protocol requires MS-CHAPv2 or EAP based authentication, make sure your connection settings comply, see below: Error Code:812 Error Description: 812: The connection was prevented because of a policy configured on your RAS/VPN server.

connection fails and the following error is displayed: Error http://www.cryer.co.uk/brian/windows/troubleshooting/w7_error_812_vpn_prevented_because_of_policy.htm 812: The connection was prevented because of a policy configuration on your RAS/VPN server. Specifically the authentication method used by the server to verify your username and password may not match the authentication method configured in your connection profile. Please contact the Administrator of the connection the RAS server and notify them of this error. Cause: This error indicates that the attempt to establish a VPN connection was rejected by the server. Possible Remedies: Check the the user account has been granted permission to connect via VPN, as this the connection was error will be generated if the account has been set to deny access to VPN.On the Server run Active Directory users and Computers. Navigate down to the account in question and open up its properties. On the "Dial-in" tab check that under "Remote Access Permissions (Dial-in or VPN)" that "Allow Access" is selected. If it is not then change it and Apply the update. These notes have been tested with clients running Windows 7 and with a VPN server on Windows 2003 Server, and they may also apply to other versions of Windows.
