The Reporting Engine has its own service that runs in the background. This service is the web server that actually serves the HTML reports and the complete datasets to the client application. The service can be seen and controlled in the Windows Operating System under Administrative Tools | Services.
The Reporting Engine service can also be controlled through the Processing Engine Administrator. In the main menu, simply select Reporting Engine | Start to start the service and Reporting Engine | Stop to stop it. Until the service has started, the administration interface will not be accessible, because it is the service itself that serves that web-based interface.
