Hi,
Just wondering if anyone can help.
We have set up RAS/VPN on our Windows Server 2012 Essentials server. One of our users when trying to log in gets the below error when trying to connect to VPN:
"Error 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 RAS server and notify them of this error."
The domain admin account can log in to VPN fine and any new AD account that I create can log in fine, but just not this particular user account. I checked that this account has "Dial In" access on their user account on AD and on the Anywhere Access
tab on the users properties in Windows server 2012 Essentials Dashboard the "Allow Virtual Private Network (VPN)" is ticked. They are a member of the RA_AllowVPNAccess security group.
I also configured the authentication protocol MS-CHAPv2 on the server and on the client. I also tried to connect using PPTP rather than automatic, with no luck.
I 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. 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.
I'm buffled why just this user cannot connect to VPN.
Any thoughts?
