Login failed for user ‘NT AUTHORITY\SYSTEM’. [CLIENT: ]

    Problem

    You receive hundreds if not thousands of NT Authority\SYSTEM "Login failed for user ‘NT AUTHORITY\SYSTEM’. [CLIENT: <local machine>]" error messages

    clip_image001

    Errors often occur every minute

    clip_image002

    Explanation

    You’ve probably deleted your Shared Service Provider or created a new one. Unfortunately, some scheduled jobs will remain on your SQL server that reference the now defunct database.

    Solution

  • Launch SQL Server Management Studio and connect to the server that houses your Shared Service Provider
  • Within SSMS expand the SQL Server Agent and select jobs.
  • Locate the jobs that have names that end in "_DeleteExpiredSessions"
  • clip_image003

  • You in the "Steps" tab double click on the first step and check to see if there’s a database, if there’s no database selected you’ve probably deleted said database so you can safely disable the job.
  • clip_image004

  • If you don’t understand these instructions or are confused then STOP! Disabling SQL jobs is dangerous business and can cause undesired outcomes.

      Do you have any SharePoint Designer workflows that you created while logged in as a System Administrator or SharePoint Application Pool account? I have noticed that this can cause problems as well.

    Worked like a champ!!!

    Was able to locate the stale SQL job and disable it very quickly using your screenshots.

    Thank you so much!
