Why can't I manually stop the FAX service in Windows 2000?

A. Win2K's built-in FAX service doesn't run constantly. Instead, the service starts when an application requires the service. As a result, when you attempt to manually start and stop the service, you receive the following error:

NET STOP FAX

The Microsoft Fax Service service is not started.
