XenApp 6 – Disconnecting ICA session attempts to restart the server

System: XenApp 6 on Windows 2008 R2

Event description:

“The attempt by user domain\user to restart/shutdown computer XXXXXXXXXXX failed”

Event id: 1073 Source USER32

This event is generated when a user logs off from an ICA or RDP session. There is no actual attempt to restart or shutdown by a user or apps. The event is generated immediately after the log off.


  • Open the RemoteApp Manager (Under Administrative tools – Remote Desktop Services) as admin user. 
  • Close the RemoteApp Manager Console.
  • Clear the system log from event viewer.
  • Now you should not see the event anymore.
