Overview and Installation – SQL Server Reporting Services 2012 - Learning SQL Server Reporting Services 2012 - page 43

Using the Configuration tool is the recommended (best) practice, if you need to
make changes to the Report Server installation. Later on, you will see how the
configuration is carried out when the Report Server is installed in the SharePoint
Integrated mode.
The service account provided during installation passes to the Report Server as
well. It is possible to change the password or use a different account as described
previously. For the purpose of this topic, the default account will be used. Also, as
the Report Server will not be deployed on a network, we will not be concerned with
registering a Report Server Service Principal Name with the domain user account.
Interested readers, who may want to pursue this, should look up Register a Service
Principal Name (SPN) for a Report Server in the Microsoft SQL Server documentation,
or if you have created a local help library look for it at C:\Program Data\
Microsoft\HelpLibrary\catalogs\SQLSERVER .
Reporting Services uses an encryption key to secure data in the Report Server database.
Changing the account or password involves saving the backup encryption key-related
information. We will be using the service account and password we supplied during
the SQL Server installation, and do not intend to change them. However, to guard
against any untoward event, we have carried out a backup of the encryption key.
Using browsers you can access the Report Server Web Service URL as well as the
Report Manager URL, as seen earlier. To use any of these, at least one URL should be
configured for each instance of Report Server and Report Manager. Since the Native
mode for Reporting Services was chosen during the SQL Server 2012 installation,
the reserved URLs are configured with default values automatically. You may also
choose custom values. For this topic, however, the defaults are accepted. Since Port
80 is used by the IIS 7.5 as well as the SharePoint Server site, there is a contention
that can be managed by setting a different port.
