ODBC access to an informix database from WinNT 4.0

I am trying to get an ODBC connection to my informix database (v5.04) from a WinNT 4.0 platform. I've installed Informix-Connect, configured the Setnet32 server and host information and verified that I can get a connection to the server using the ILogin demo (at least the ILogin demo does not return any errors when I tell it to access my database), and I get the "Customer Records Found" window returned. I've also installed the Intersolv 32 bit ODBC drivers (v3.01) and configured a system DSN. This configuration looks correct although it has not been tested (I have not found a way to do this yet). I'm doing my development in Cold Fusion, and in the Cold Fusion administrator under the Data Sources, I can see that the data source is available, but when I tell it to verify it I get the following error message: The conection to the data source failed. Check the data source settings as well any security privileges required to access your database. Can anyone out there provide any clues or suggestions... Thanks Jon Gjerset Nuera Communications.
