rsConfig utility for resetting the rsReportServer.config encrypted settings

Here's a good error that will require use of rsconfig:

The report server cannot open a connection to the report server database. A connection to the database is required for all requests and processing. (rsReportServerDatabaseUnavailable).

This error occurs when the report server cannot connect to the SQL Server relational database that provides internal storage to the server. The connection to the report server database is managed through the Reporting Services Configuration tool. You can run the tool, go to the Database Setup page, and correct the connection information. Using the tool to update connection information is a best practice; the tool ensures that dependent settings are updated and that services are restarted. For more information, see Configuring a Report Server Database Connection and Configuring Service Accounts and Passwords in Reporting Services http://msdn.microsoft.com/en-us/library/ms160340.aspx.

This error can also occur if the Database Engine instance that hosts the report server database is not configured for remote connections. Remote connection is enabled by default in some releases of SQL Server 2005. To verify whether it is enabled on the SQL Server Database Engine instance you are using, run the SQL Server Surface Area Configuration tool. You must enable remote connections for both TCP/IP and named pipes. A report server uses both protocols. For instructions on how to enable remote connections, see the section "How to Configure Remote Connections to the Report Server Database" in Configuring a Report Server for Remote Administration http://msdn.microsoft.com/en-us/library/ms365170.aspx.

If the error includes the following additional text, the password expired on the account used to run the Database Engine instance: "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not permit remote connections. (provider: SQL Server Network Interfaces, error: 26 - Error Locating Server/Instance Specified)." To resolve this error, reset the password.

Product: SQL Server Reporting Services
ID: rsReportServerDatabaseUnavailable
Source: Microsoft.ReportingServices.Diagnostics.Utilities.ErrorStrings.resources.Strings
Version: 8.00
Message: The report server cannot open a connection to the report server database. A connection to the database is required for all requests and processing.
Explanation
This error occurs when the report server is unable to connect to the report server database. The rsreportserver.config file stores encrypted values for the database name and credentials that it uses to connect to the report server database. If the database name or credentials have changed, the report server can no longer connect to the database.

User Action
You can use the rsconfig utility to update or repair the configuration settings that the report server uses to connect to the report server database. You can use the -d option of the utility to set the name of the report server database and you can use the -u and -p options to set the username and password. For information about how to use the rsconfig utility, see Books Online.

rsconfig –c for the encrypted connection settings –e for the encrypted unattended account settings -m computername that RS resides on –i RS instance name –s server name that the database resides on –d RS database name –a authentication method which is either "windows" or "sql" -u username -p password (-t trace)

rsconfig -? will show you the syntax
