I went back and changed the name of the SQL server from AppVolMgr\SQLEXPRESS to AppVolMgr (Figure 11); after doing so, I was able to select the View Composer database and successfully set up an ODBC ...

If the server is a Windows-based machine, begin the IP address or hostname with the "smb://" prefix. Click on the "Connect" button to initiate a connection.

The Connection Properties dialog opens. For my sample ITworld application, I changed the data source to Microsoft SQL Server (SQLClient), and entered the necessary Server, Log On, and database values.
