I just added msSQL 2014 to a new computer running Windows 7 and CF 11
I opened the port 1434 and when I tried to connect the datasource in CF Admin got this message...

Verify the server and instance names, check that no firewall is blocking UDP traffic to port 1434, and for SQL Server 2005 or later verify that the SQL Server Browser Service is running on the host.
