Shuts down (and optionally restarts) the specified Remote Desktop Session Host (RD Session Host) server.
- hServer [in]
Handle to an RD Session Host server. Specify a handle opened by the WTSOpenServer function, or specify WTS_CURRENT_SERVER_HANDLE to indicate the RD Session Host server on which your application is running.
- ShutdownFlag [in]
Indicates the type of shutdown. This parameter can be one of the following values.
Forces all client sessions to log off (except the session calling WTSShutdownSystem) and disables any subsequent remote logons. This can be used as a step before shutting down. Logons will be re-enabled when the Remote Desktop Services service is restarted.
Use this value only on the Remote Desktop Services console.
Windows Server 2003: This value does not log off the Remote Desktop Services console session. Note that this session is not present as of Windows Vista.
Shuts down the system on the RD Session Host server and, on computers that support software control of AC power, turns off the power. This is equivalent to calling ExitWindowsEx with EWX_SHUTDOWN and EWX_POWEROFF. The calling process must have the SE_SHUTDOWN_NAME privilege enabled.
Shuts down and then restarts the system on the RD Session Host server. This is equivalent to calling ExitWindowsEx with EWX_REBOOT. The calling process must have the SE_SHUTDOWN_NAME privilege enabled.
Shuts down the system on the RD Session Host server. This is equivalent to calling the ExitWindowsEx function with EWX_SHUTDOWN. The calling process must have the SE_SHUTDOWN_NAME privilege enabled.
This value is not supported currently.
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
A system shutdown terminates all users and active programs. The following steps occur during shutdown.
- An exit command is issued to all active user applications.
- If the application does not exit within a specific interval, the application is terminated.
- After all the applications for a user terminate, the user is logged off.
- After all users are logged off, an exit command is issued to all system services.
- If the system service does not terminate within a specific interval, the service is terminated.
- The file system cache is written to disk.
- The disks are marked read-only.
- The RD Session Host server displays the message "It is now safe to turn off your computer", or the system is restarted if WTS_WSD_REBOOT is specified. (The message is displayed on the console because all client sessions have been terminated.)
Windows Server 2008 and Windows Vista: A call to WTSShutdownSystem does not work when Remote Connection Manager (RCM) is disabled. This is the case when the Remote Desktop Services service is stopped.
