If you are going to an Easysoft ODBC-ODBC Bridge data source, this is due to bug ID 1394 in the ODBC-ODBC Bridge, which is fixed in release 1.0.0.41. You must either upgrade Easysoft ODBC-ODBC Bridge or install the XML-ODBC server on the machine where the target ODBC driver is located. You do not need the ODBC-ODBC Bridge in this case.
