Query Editor Connection Error With Unattended Service Account
I found this post while researching the same error message.
I am using 'SQL Server Data Tools for Visual Studio 2017’ My database is on SQL 2017, Enterprise.
The problem turned out to be that the credentials switched to &quot;Do not use credentials&quot; After I set it to &quot;Use Windows Authentication&quot; when I created the data source.
I changed it back (below) and saved, problem solved.
