The Shutdown Event Tracker, a new Windows Server 2003/2008 feature, is an uncomplicated GUI application that allows administrators to monitor shutdown events on the server. This tool is enabled on Windows Server 2003/2008 by default. The Shutdown Event Tracker collects information on the reasons why the server was shut down, and then logs this information in Event Viewer. The command-line utility equivalent to the Shutdown Event Tracker is Shutdown.exe.
The Shutdown Event Tracker requires you to provide a reason whenever a server is shut down or restarted. When a server is expectedly shut down, a dialog box or page is displayed, requesting you to specify the reason for the server being shut down. When a server is unexpectedly shut down, the following user to log on to the server has to specify the reason for the server shutting down. Shutdown events can be viewed in Event Viewer, and can be useful when you need to improve uptime.
