I installed ColdFusion 2018 on our Windows 2012 sandbox server with SQL Server 2012 Express installed.  I am able to configure several datasources using the CFAdmin which shows OK as the status.  But when I try using the connection in a cf page from CFBuilder, I get the error,

Datasource AP2 could not be found.

1 : // script
2 : <cfscript>
3 :     myquery = QueryExecute('SELECT * FROM artists', [], {datasource = 'AP2'});
4 : </cfscript>
5 :

The datasource does exist and shows valid, also SQL Server is configured to allow TCP/IP connections:

Can anyone suggest what could be stopping the CF code from seeing the datasource?  BTW, I am using a named server:  “1029823-SANDBOXSQLEXPRESS” instead of the 127.0.0.1 as the Server in the configuration.

Thanks in advance for any help!
