SystemShutdown From Within a Service

[mccartmd]

I am trying to shut down a Windows 2000 machine from within a service without success. The system will shut down fine if ran as a standalone process, but if it is run through a running service, it will only get as far as the "Shutting down Windows" screen. Does anyone have any advice as to how I can shut down the system?

Thanks in advance for any suggestions.

Services on NT boxes run under different privileges than normal applications. There is an option when you create a service for it to a "interact with desktop", you need to make sure that this is set.

By default it is running under a standard local system account.

If the above still doesnt work you can try running the service as administrator by supplying the admin name and password.

I dont know if this applies to windows 2000 but under XP there is a program called shutdown which you can call from the command line. this program takes arguments like, force, time out, message etc. So you can force a computer to shutdown. but again you need to be logged in as the administrator.

To be more specific, I was asking about shutdown though code:

We have a service that we coded, and when the service receives a message to shutdown, it will only get as far as "Shutting Down Windows..." and hangs. We have determined that it hangs there because the shutdown code runs from within the service. If we run the code as a stand alone application, the computer shuts down fine. My question is if there is some specific coding we must do to make the computer shutdown completely. Thanks for suggestions.

Try to call CreateService() with SERVICE_WIN32_OWN_PROCESS | SERVICE_INTERACTIVE_PROCESS by creating the service.
