As everyone knows with the introduction of Windows Server 2012 & 2012 R2, there are various changes and no more availability for RDSH configurations or Remote Desktop Service Manager;
now we can manage all the settings under Server Manager and group policy.
Configuration 1: Remote Desktop Timeout settings:
Here, we will see the Remote Desktop timeout settings. You can maintain the settings under below mention path (Figure 1 and Figure 2).
- Open the
Server Manager, select Remote Desktop Services.

Group policy setting:
The same settings can also be applied by Group Policy.
You can also configure timeout and reconnection settings by applying the following Group Policy settings, you can check the figure 3 for graphical view.
- Set time limit for disconnected sessions
- Set time limit for active but idle Remote Desktop Services sessions
- Set time limit for active Remote Desktop Services sessions
- End session when time limits are reached
In addition to this another group policy available with the help of which you can bale to set time limit for logging off the RemoteApp according to our desired time. This setting
can be applied with addition to above mentioned policy.
- Set time limit for logoff of RemoteApp Sessions
These Group Policy settings are located in the following locations:
Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Session Time Limits
User Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Session Time Limits
These Group Policy settings can be configured by using either the Local Group Policy Editor or the Group Policy Management Console (GPMC).
Note:
These Group Policy settings will take precedence over the settings configured in Remote Desktop Session Host Configuration. If both the Computer Configuration and the User Configuration policy
settings are configured, the Computer Configuration policy settings take precedence.
