Are you using CWBODBC.DLL (v13.00.01 is what I have) to connect to DB2? Normally I use IBM.Data.DB2.iSeries since we are in .Net (though we have also used OleDb), but have needed IBM's ODBC driver to export from Access. But maybe your DB2 install isn't on iSeries/AS400 - not sure if that makes a difference.
