SQL Server Agent is a Windows service that executes the scheduled administrative jobs such as index maintenance, update statistics, database integrity checks, in addition to the application specific jobs. The SQL Server Agent service must be running in order for these job to executed on their scheduled time. What if you are working on an application upgrade that requires you to stop the SQL Server Agent from running and then restart it once the upgrade is completed? What are the commands to stop the SQL Server Agent and start it? Is there any script to check if the SQL Server Agent is running? In this blog, we will explore and share with you on how can we quick stop, start, and run a script to check the SQL Server Agent status.
You can start and stop the SQL Server Agent by using the SQL Server Configuration Manager or the Command Prompt Window using the net commands. We will explore both options here.
Using SQL Server Configuration Manager to start and stop SQL Server Agent:
Open the SQL Server Configuration Manager by running the corresponding Microsoft Saved Console (msc) file for the version of SQL Server you are running:
- SQL Server 2005: SQLServerManager.msc
- SQL Server 2008 and 2008 R2: SQLServerManager10.msc
- SQL Server 2012: SQLServerManager11.msc
- SQL Server 2014: SQLServerManager12.msc
- SQL Server 2016: SQLServerManager13.msc
For example, I am running SQL Server 2012 on our demo server, I will run the “SQLServerManager11.msc” file in the “Search programs and files” textbox:
The SQL Server Configuration Manager will open:
You can then stop, restart, or start any of the SQL Server services installed on the Windows Server.
Using Command Prompt Window to start and stop SQL Server Agent:
To stop the SQL Server Agent service from the command prompt, run the command prompt as the administrator and then key in the following command:
NET STOP SQLSERVERAGENT
To start the SQL Server Agent service from the command prompt, run the command prompt as the administrator and then key in the following command:
NET START SQLSERVERAGENT
NOTE: For named instances, add the $ symbol as in NET STOP SQLSERVERAGENT$NAMEDINSTANCE and NET START SQLSERVERAGENT$NAMEDINSTANCE.
As a SQL Server DBA, you work with multiple SQL Server instances, what if you wish to run a query to check if the SQL Server Agent is running? You can use the following query to check the SQL Server Agent status:

WHERE program_name = N'SQLAgent - Generic Refresher')
SELECT SERVERPROPERTY('ServerName') AS 'InstanceName', 'Running' AS 'SQLServerAgent Status'
SELECT SERVERPROPERTY('ServerName') AS 'InstanceName', 'Stopped' AS 'SQLServerAgent Status'
In the following section, we will stop the SQL Server Agent service, run the query to check its status, start it, and then run the query to check its status again.
Stop the SQL Server Agent Service using the NET STOP SQLSERVERAGENT command.
Run the “SQLServerAgentServiceStatus.sql” script to check the SQL Server Agent service status. It will show “Stopped”.
Start the SQL Server Agent Service using the NET START SQLSERVERAGENT command.
Run the “SQLServerAgentServiceStatus.sql” script to check the SQL Server Agent service status. It will show “Running”.
If you wish to check the SQL Server Agent status for multiple instances, you can register all the required instances and then run a multiple server query. For example:
