Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC Driver Manager]Data source name not found and no default driver specified.

This usually happens in one of the following scenarios:

* you referenced your connection incorrectly (e.g. spelled the DSN name, or one of the DSN-less string components wrong);
* you referenced a DSN that doesn't exist;
* the user connecting to the DSN or DSN-less connection doesn't have access to the information stored in the registry (see KB #306345);
* you used an English or localized driver detail for your connection string when your system is not set up in that language (see KB #174655); or,
* you are missing the connection string entirely (this can happen if you maintain your connection string in a session variable, and your sessions aren't working; see Article #2157).
