CRAXDRT error - Crystal Reports ASP Script

I am using Crystal RDC components with asp script to open report in browser
viewer crystal plugin. I have other sample reports that work fine. This
report has a few parameters prompted before running the report.
Configuration is Windows server 2003 with all recent updates applied.

Error I receive when running report is as follows:

CRAXDRT Error Occured on Server. -2147189176 : Logon Failed. Details:
Database Vendor Code: -329

Database is Informix with odbc System DSN setup on this webserver. Testing
connection through odbc panel works fine. Checked asp file and
authentication info is correct......

Any help would be appreciated.

Thanks,
Bob
