When trying to create a database within a domain you get an error
and the following in the error log:
16/07/2003 2:27:50 PM Microsoft OLE DB Provider for ODBC Drivers [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
16/07/2003 2:27:50 PM CDatabase.CreateDatabaseEx Automation error. Unspecified error
Depending on which version of MySQL you are using, you will need different drivers.
For MySQL 4.0 - you need MyODBC 2.5 drivers, downloadable here:
For MySQL 4.1 - you need MyODBC 3.51 drivers, downloadable here:
Please note: for MySQL 4.0 - you will also need the 3.51 MyODBC drivers on your server if you want to create a DSN. This is because 2.5 is used by Helm to create users and databases, but 3.51 is used for the DSN connections.
