SQL database login for ‘SHAREPOPINT CONFIG DB NAME’ on instance ‘SQL INSTANCE NAME’ failed. Additional error information from SQL Server is included below.

Login failed for user ‘Web Front End SERVERNAME$’.

The reason why i mentioned these two events are together is that the resolution below that i did is related to the two error events. If your event log does not contain these two errors, it is likely that the resolution below may not work for you.

Resolution

  1. Go to the server that contain these error message (Web Front Event server).
  2. Open IIS (Internet Information Services) Manager
  3. In the Connections panel, navigate to Application Pools
  4. (In my case, the “SecurityTokenServiceApplicationPool” Application Pool is running using “LocalSystem” account)
  5. Select the SecurityTokenServiceApplicationPool and click “Advanced Settings” from the action panel.
  6. Scroll to ProcessModel section and change the Identity to YOUR SharePoint Farm Account!
  7. Click Ok and Recycle the application pool and done!
