uint32 StopService();

Parameters

This method has no parameters.

Return value

Returns one of the values listed in the following list, or any other value to indicate an error. For additional error codes, see WMI Error Constants or WbemErrorEnum. For general HRESULT values, see System Error Codes.

0: The request was accepted.
1: The request is not supported.
2: The user did not have the necessary access.
3: The service cannot be stopped because other services that are running are dependent on it.
4: The requested control code is not valid, or it is unacceptable to the service.

Remarks

After you have determined which services can be stopped or paused, you can use the StopService and PauseService methods to stop and pause services. The decision to stop a service rather than pause it, or vice versa, depends on several factors, including the following:

Is the service capable of being paused? If not, your only option is the stop the service.
Do you need to continue handling client requests for anyone already connected to the service? If so, pausing a service typically allows it to handle existing clients while denying access to new clients. By contrast, when you stop a service, all clients are immediately disconnected.
Do you need to reconfigure a service and have the changes take effect immediately? Although service properties can be changed while a service is paused, most of them do not take effect until the service is actually stopped and restarted.

The scripting code required to stop a service is almost identical to the code required to pause the service.

If you attempt to stop a service which has dependent services running, the StopService method fails with a return value of 3. The dependent services must be stopped first.

If you stop a service, then immediately check the Win32_TerminalService.State property, as the value may still show the service as running.
