How to disable warning message for idle remote desktop sessions

Applies to:   Windows Servers

When a remote desktop session idle session limit is exceeded, a warning message is displayed and the session is disconnected after two minutes. If you want the session to be disconnected immediately and without a warning message, set the EnableTimeoutWarning property of the Win32_TSSessionSettings WMI class to 0 by using the following PowerShell cmdlet from an elevated PowerShell prompt (as an administrator):

Note

This change takes effect only after active sessions are disconnected and reconnected.

Set-WmiInstance -Path "\\localhost\root\CIMV2\TerminalServices:Win32_TSSessionSetting.TerminalName='RDP-Tcp'" -Argument @{EnableTimeoutWarning=0}

You can determine the idle session limit by using the following PowerShell cmdlet:

Get-WmiObject -ComputerName localhost -Namespace root\CIMV2\TerminalServices -Class Win32_TSSessionSetting  -filter "TerminalName='RDP-Tcp'" | select IdleSessionLimit

Note

• The EnableTimeoutWarning property has been deprecated for third-party protocol providers starting from Windows 10, version 2004 and Windows Server, version 2004. Contact the protocol provider for help to enable or disable the warning message.
• If a third-party protocol provider is used, replace "RDP-Tcp" with the relevant protocol name for the provider.
• If you're running the cmdlet remotely, make sure the server's firewall allows WMI access and replace "localhost" with the server's name.
