    .DESCRIPTION
        This example installs to instances where the first named instance is used for
        the Reporting Services databases, and the second named instance is used for
        Reporting Services. After installing the two instances, the configuration
        performs a default SQL Server Reporting Services configuration. It will
        initialize SQL Server Reporting Services and register the default
        Report Server Web Service and Report Manager URLs:

        Report Manager: http://localhost:80/Reports_RS
        Report Server Web Service: http://localhost:80/ReportServer_RS
