What do I need to do in order to connect client apps to the Informix database??

Any information or experience with connecting 16 bit applications (Cognos/Impromptu) running on Windows NT 4.0 to Online 7.2 or XPS? Informix does not support I-NET for Windows running on Window NT, yet have said I-NET will work on Windows NT. The error message is Informix number -932: A general exception has occurred during operation 'attach database'. Error on network connection, unknown connection problem system call failed. I can connect and attach to the database through DBACCESS on the server. I can ping the host and have added the INFORMIXDIR variable and C:\\INFORMIX to the path in Windows NT. The service name and host name on client and server are ok Client Config Informix-Net 5.01 Informix-CLI 2.50 Q+E ODBC (16 bit Driver 2.5 QEINF509.DLL) Protocol - Windows Sockets (winsock.dll) Server Online ODS 7.2 AIX ANY help would be greatly appreciated!!
