A report server is implemented as a Windows service that contains the Report Server Web service, Report Manager, and a background processing application. The service must be running if you want to use any report server functionality. Stopping the service stops all report server operations.
While the service is stopped, requests for scheduled report and subscription processing that would have occurred had the service been running are added to the queue. This is because jobs that are run by SQL Server Agent create the events. If you want to avoid a backlog of operations while the service is off, consider stopping SQL Server Agent as well.
You can use a variety of tools to start or stop the Report Server service, including the Reporting Services Configuration tool, SQL Server Configuration Manager, and the Services tool provided in Microsoft Windows.
If you are doing more than starting or stopping the service, such as changing the service account, you must use the Reporting Services Configuration tool. Using other tools to change the service account can break your Reporting Services installation. For more information, see Configure the Report Server Service Account (SSRS Configuration Manager).
You cannot pause and resume the service. There are no start parameters. Although there are no explicit dependencies, SQL Server Agent must be running if you support any subscriptions or scheduled report operations on the report server.
To start or stop the service using the Reporting Services Configuration tool
Start Reporting Services Configuration tool and connect to the report server.
On the Report Server Status page, click Stop or Start.
To start or stop the service using Services in Administrative Tools
In Administrative Tools, open Services, right-click SQL Server Reporting Services (MSSQLSERVER), and click Stop or Restart.
If you are running multiple instance or if the report server is running as a named instance, verify that the instance name in parentheses corresponds to the report server instance you want to stop or restart.
To start or stop the service using SQL Server Configuration Manager
Start SQL Server Configuration Manager.
Select SQL Server Services, right-click SQL Server Reporting Services, and click Stop or Restart.
