Where are you looking to see the OLE DB providers? If you're creating a DSN (System, File, or User) you won't see the providers because DSNs use ODBC. Data Link files use OLE DB and you can create one of those to see what providers are on your machine. To create one just create a text file but give it a UDL extension. Double-click it and you'll be able to set up the OLE DB connection information.
