Error Code: 18452 - Invalid logon parameters

Question

We are trying to schedule several crystal reports to run automatically on our server and continue to get the following errors.
Invalid log on parameters Database Vendor Code:  18452
When we review the log in Crystal Report Viewer we are receiving the following information.
The database logon information for this report is either incomplete or incorrect.   
Unable to retrieve Object.
Would anyone be able to tell us what is causing these error codes?

Answer 1

We resolved the error by changing the logon paramater within our ODBC datasource connection.   When the crystal report was original created it was using the designers logon credentials to connect to the data source.  In order to fix this we had to change the logon parameter to the datasource logon.   The easiest way we determined that it was using the designers credentials (UserID/password) was by opening up the "set database location" tool and then we opened up the properties; there is where we seen the UserID of the designer.   To change this you might need to create a new connection and then update using the database expert and the set database location tools.
