I'm trying to move a SQL based app to a new server (Server 2016 STD VM). The app vendor is helping me. SQL is running and the databases are connected, but the instance of new SQL server does not show in the drop down list on the workstations and the connection fails if you type in the path. The vendor configure all of the regular firewall rules, but nothing works. Any idea of what might be missing?
Old app is running on Server 2008R2 with SQL Express 2008, new server is running SQL Express 2017
This is the error I get when I try to connect: Test connection failed because an error in initializing provider. [DBNETLIB][ConnectionOpen {connect()}.]SQL Server does not exist or access denied.
The vendor is saying there is something wrong with how the server is setup and kind of left me hanging. He's looking into it. My migration is stopped...
