Configure the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Session Time Limits -> "Set time limit for active but idle Remote Desktop Services sessions" to "Enabled", and the "Idle session limit" to 15 minutes or less, excluding "0", which equates to "Never".
