Logons are re-enabled when you restart the system. If you are connected to the Remote Desktop Session Host (RD Session Host) server from a client session and disable logons, and then log off before re-enabling logons, you will not be able to reconnect to your session. To re-enable logons from client sessions, log on at the console.

change logon /query
-
