After the Windows Server 2008R2 was restarted after some planned downtime, the SQL Server Agent Service is not getting started. There are multiple SQL Server named instances and Agent Services of non are getting started. SQL Server Version: SQL Server 2008 SP3

Please note the following errors: 1. When starting from Configuration Manager, following error is generated in Event Viewer.

The SQL Server Agent service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion.

A timeout was reached (30000 milliseconds) while waiting for the SQL Server Agent service to connect.

  1. When starting from SSMS (by right click Agent Service > START)

See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging ************** To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.

For example:

When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.

  1. When checking SQLAGENT.out file:

SQLServer Error: 65535, SQL Server Network Interfaces: Error getting enabled protocols list from registry [xFFFFFFFF]. [SQLSTATE 08001]

[165] ODBC Error: 0, Login timeout expired [SQLSTATE HYT00]

[298] SQLServer Error: 65535, A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online. [SQLSTATE 08001]

[382] Logon to server 'xxx' failed (ConnUpdateStartExecutionDate)

Workarounds already tried: 1. Changing the logon accounts to other domain users account and localsystem, networkservice etc, still same error. 2. Tried this solution from Microsoft Support https://support.microsoft.com/en-in/help/922918/a-service-does-not-start-and-events-7000-and-7011-are-logged-in-window, but still same error.

Please suggest how to resolve this issue.

  • Did you see this one? – SqlWorldWide Jul 3 '18 at 12:22
  • Yes @SqlWorldWide I have tried this. Same error. – Shaurya S Jul 3 '18 at 12:31
  • Have you tried adding the agent account to the local admins group, just to make sure it is not a rights issue – Stijn Wynants Jul 3 '18 at 12:54
  • What was done during the maintenance window? – Jacob H Jul 3 '18 at 13:22
  • Has the servername got changed in SQL Agent properties or registry? Right click on SQL Server agent and click on properties. Go to connections tab and see what servername is given there. If it is incorrect, try changing it to correct one or keep it blank and then try starting SQL Agent service to see if its working. – SQLPRODDBA Jul 3 '18 at 14:05

If this issue happens only during startup and service starts fine while starting manually then we can try to increase the timeout from 30 seconds to 60 seconds. Here are the steps to change the timeout value. SQL SERVER Timeout error

Did you set the service to start as Automatic (delayed)? If not check it once sometimes dependent components (disk drives, network shares etc..) take longer time to start up.

If this is not working, this issue happens because the SQL Server lost the logon id credentials or used an account without rights to start services. If you miss login credentials need a reboot of your windows server.

SQL Server needs an account with rights to start services during operating system start up, for starting your services automatically.

To solve this issue you need to go Administrative Tools -> Services -> SQL Server(MSSQLSERVER or the name of your instances) -> Right Click -> Properties -> Move to Log On -> Set the Log On option using a Local System Account

If you have chosen this option, hit on Browse Button and find the Local Service Account or Network service Account there > Click in Apply.

Restart your computer and you will able to start your SQL Server services.

  • Have already tried all these, but no success. – Shaurya S Jul 4 '18 at 2:34
