SQL Server Agent will not start after upgrade

  • Yesterday I upgraded a Windows Server 2008 R2 server from SQL Server 2005 SP4 to SQL Server 2008R2 SP2 in place. SQL Server runs fine, but SQL Server Agent will not start with the error "Error 2: The system cannot find the file specified". The system event log shows this error as coming from the Source Control Manager, with event ID: 7000 with keyword Classic.

    During the installation yesterday this error was found in the Application Event log:

    ".NET Runtime Optimization Service (clr_optimization_v4.0.30319_64) - Failed to compile: C:\Program Files\Microsoft SQL Server\100\DTS\Binn\dtsinstall.exe . Error code = 0x800700d8"

    Any assistance will be greatly appreciated.

  • check the windows application log for more detail

  • I did - the one message is above.

  • Did You change sql agent service account? If so, check if that account has permission on Bin folder.

  • You can try above two things:

    1. Reboot the windows server

    2. check permissions for agent service. check if it has required permissions to log on.

  • I encountered a similar error recently while upgrading from 2008 to 2008 R2. In our case, it was because the Agent account was entered using the oldschool format of accountname@domain instead of domain\accountname. Once we changed it the Agent started just fine.
