Default Behavior

Fax is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Fax service is started, it is running as NT AUTHORITY\NetworkService in its own process of fxssvc.exe. If Fax fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the Fax service is not running because of the error.

Dependencies

Fax is unable to start, if at least one of the following services is stopped or disabled:
