How to set time limit for disconnected sessions Windows Server 2012R2

By default, Remote Desktop Services allows users to disconnect from a remote session without logging off the server 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. A disconnected session continues to consume server resources and we recommend that you set policies to end disconnected session after a period of time. Sessions are ended/closed out if the user Logs Off from the server (start -> logoff) but are not ended if the user simply clicks the X in the upper corner to close the RDP window.

You can limit the amount of time that active, disconnected, and idle sessions remain on the server. Two methods are described below:

#1 — User Properties to set session time limits per user:

In each user’s properties window, under sessions tab, you can change the default of “end a disconnected session” from NEVER to X hours/days as well as change the other settings.

#2 — Group Policy to set session time limits for all users:

  1. Cmd prompt, gpedit.msc
  2. Computer Configuration, Admin Templates, Windows Components, Remote Desktop Services, Remote Desktop Session Host, Session Time Limits
    1. Enable appropriate group policies and modify as needed
    2. We recommend setting this one because it will prevent disconnected sessions from consuming server resources — “Set time limit for disconnect sessions”
  3. After modifying group policies, you can force an update without rebooting by typing “gpupdate /force” at cmd prompt

 

#3 — If Windows Server 2008R2, you can modify these settings in RD Session Host Configuration too

To configure session settings on a windows 2008R2 server with Remote Desktop Services role installed, go to start -> administrative tools -> remote desktop services -> RD Session Host Configuration. Then right click RDP-Tcp properties, Sessions tab, and enter value to end a disconnect session after a specific period of time, end an idle session, etc. (tsconfig.msc also opens the RD Session Host Configuration window).
