End user uses remote desktop connection to log on to a 802.1x secured Windows 7, Windows 8 or Windows 10 machine that is configured user authentication only. After about one minute, the connection is lost, and the user are unable to re-establish the remote connection. A local (console) logon may resolve the issue.

When 802.1x authentication mode is configured to user authentication, the supplicant fails to query the user token in the remote desktop session.

To make remote desktop connection works with 802.1x authentication, we must use computer authentication or "User or computer authentication"
