The Set time limit for disconnected sessions machine setting should be configured correctly. This policy setting allows you to configure a time limit for disconnected Remote Desktop Services sessions. You can use this policy setting to specify the maximum amount of time that a disconnected session is kept active on the server. By default, Remote Desktop Services allows users to disconnect from a Remote Desktop Services session without logging off and ending the session. When a session is in a disconnected state, running programs are kept active even though the user is no longer actively connected. By default, these disconnected sessions are maintained for an unlimited time on the server. If you enable this policy setting, disconnected sessions are deleted from the server after the specified amount of time. To enforce the default behavior that disconnected sessions are maintained for an unlimited time, select "Never". If you have a console session, disconnected session time limits do not apply. If you disable or do not configure this policy setting, disconnected sessions are maintained for an unlimited time. You can specify time limits for disconnected sessions on the Sessions tab in the Remote Desktop Session Host Configuration tool. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Session Time Limits\Set time limit for disconnected sessions (2) KEY: HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\MaxDisconnectionTime
