Module Name:

    Shutdown.c

Abstract:

    This module contains the server side implementation for the Win32 remote
    shutdown APIs, that is:

        - BaseInitiateSystemShutdown
        - BaseAbortSystemShutdown
        - BaseInitiateSystemShutdownEx

Author:

    Dragos C. Sambotin 18-May-1999

Notes:
    
    These server side APIs are just stubs RPCalling in the winlogon's shutdown
    interface. They are provided only for backward compatibility. When support 
    for older versions is dropped, these stubs can be removed.

Routine Description:

    This routine is provided for backward compatibility. It does nothing    

Arguments:

    ServerName - Name of machine this server code is running on. (Ignored)

    lpMessage - message to display during shutdown timeout period.

    dwTimeout - number of seconds to delay before shutting down

    bForceAppsClosed - Normally applications may prevent system shutdown.
              - If this true, all applications are terminated unconditionally.

    bRebootAfterShutdown - TRUE if the system should reboot. FALSE if it should
              - be left in a shutdown state.

Return Value:

    Returns ERROR_SUCCESS (0) for success; error-code for failure.
