1218357 - Error: "Logon failed" when attempting to change database in .NET application

Symptom

An application uses the Crystal Reports 10 .NET SDK as the reporting development tool. When the application attempts to change the database name or server to another database of the same type, an error message similar to the following appears:

Message: "Logon failed.

Details: IM002:[Microsoft][ODBC Driver Manager] Data

source name not found and no default driver specified

Error in File

C:\DOCUME~1\lrolf\LOCALS~1\Temp\{1A27D2B6-4542-46C5-9214-DEE782C32678}.rpt:

Unable to connect: incorrect log on parameters."

Resolution

This known issue has been assigned Track ID ADAPT00353320, and affects the following:

" Crystal Reports (CR) 10

Hot Fixes or Service Packs address this issue as indicated below. With the update(s), the internal SDK method of setting a database table's location was inadvertently stripping out needed information when changing the database name or database server. The original logon properties are now kept intact and only the modified properties are replaced when changing the database.

Unless indicated otherwise, Weekly Hot Fix updates from the FTP site have only been tested with English versions of our products.
