"Data Source Name Not Found and No Default Driver Specified" message is displayed when trying to use certain tools in BRCM.
This message indicates the ODBC datasource was not created or was not configured properly or that the project .pcf file is specifying an invalid data source name (DSN).
Follow the instructions in the Bentley Raceway and Cable Management (BRCM) installation guide and use the ODBC Data Source Administrator to create a data source that BRCM will use to connect to the SQL Server database. If the data source was already created, make sure the name of the data source matches the value for DSN in the .pcf file(s) for the project(s). Typically, as directed in the installation guide, the name should be "BRCMUser".
Alternatively, use the technique described in the Configure BRCM database connect string with no ODBC DSN required article.
