I am using Crystal Enterprise 8.0 at NT server 4.0, and the report pulled the data from Oracle at Unix box. At NT server, Oracle client 8.1.6 was installed. I am using one generic user id to access Oracle from NT server, and everything is fine when the report using the ODBC driver to pull the data. To have a better porformance, I switch to the OLEDB driver at the report, then sqlnet.log file was generated saying there was a failed connection that try to connect using the user id 'system'. Actually, there is no user named 'system' at Oracle. The report got the correct data, only the misleading log file confused me. And also worried about the log file is increasing the size.
