Event ID 3760 is logged on the server as the timer job is trying to locate a non-existent database


While we access the SharePoint application server, we receive these event ID

The service application was not removed in the proper format, leaving behind orphan entries for databases.



Deleted the Orphan Entries using PowerShell

Get-SPDatabase | where {$_.name -match "<Name of the Service Database>"} | fl
$db = get-spdatabase | where {$_.id -match "<ID enumerated of the Database from above command>"}
