Event 3760 – SQL Database on SQL Server Instance not found in Event Log in SharePoint Server

Problem :The event log on my WFE is filled with errors every hour complaining that a database on my SharePoint SQL instance is not found.

Cause: This was caused by me creating and deleting a service application, and then going into SQL Management Studio and manually deleting the associated service application database. SharePoint still had a record of the database in its config database.

Solution : Delete the record of the orphaned database using PowerShell

1. Open SharePoint Management Shell
2. Type: Get-SPDatabase | fl name, id
3. Find the database you wish to remove and select its ID.
4. Type: $pp = get-spdatabase <id>
5. Type: $pp.delete()

SharePoint’s record of the database is now deleted and it should no longer complain that the database is not found.
