IssueWhen attempting to connect to a SQL data source in Tableau Desktop, the following error occurs:
[Microsoft][SQL Server Native Client 10.0][SQL Server] Server name cannot be determined. It must appear as the first segment of the server's dns name (servername.database.windows.net). Some libraries do not send the server name, in which case the server name must be included as part of the user name (username@servername). In addition, if both formats are used, the server names must match.
