We are trying to upgrade our Domain Controllers to Server 2016 from 2008 R2 and are having some issues with Radius. Server 2008 R2 works fine authenticating Windows 7 & 10 machines. With Server 2016, it works fine authenticating Windows 7, but Windows 10 machines have been unable to authenticate. We were looking through event viewer and see no logs for connection attempts from the Windows 10 machines. Only logs relevant is from the NPS accounting log file which doesn't help highlight the issue for us. The Meraki logs gives us an EAP error. Client VPN authentication from Windows 7 & 10 machines also have no trouble authenticating against this server. Granted, VPN isn't utilizing PEAP like the Wireless authentication is. Has anyone run into anything like this?
