Thanks for the reply from lbendlin.

Hi @turbobeagle18 ,

This issue occurs when at least one of the following problems exists: The TCP port number isn't specified correctly. The name of the computer hosting SQL Server is incorrect. The instance doesn't resolve the correct IP.

You can refer to the following link to troubleshoot the problem:

A network-related or instance-specific error occurred - SQL Server | Microsoft Learn

If you are using Named Pipes to connect, it fails because the user does not have permission to log on to Windows. Add the user to the Users group on the server that's running SQL Server. If SQL Server is mirrored or clustered, repeat on all computers within the group.
