Reporting Services WMI Provider Library Reference (SSRS)
The Reporting Services Windows Management Instrumentation (WMI) provider supports WMI operations that enable you to write scripts and code to modify settings of the report server and Report Manager.
For example, if you want to change whether integrated security is used when the report server connects to the report server database, create an instance of the MSReportServer_ConfigurationSetting class and use the DatabaseIntegratedSecurity property of the of the report server instance. The classes shown in the following table represent Reporting Services components. The classes are defined in either the root\Microsoft\SqlServer\ReportServer\<InstanceName>\v11 or the root\Microsoft\SqlServer\ReportServer\<InstanceName>\v11\Admin namespaces. Each of the classes support read and write operations. Create operations are not supported.
