Improved error messages about missing OLEDB providers
We've modified the OLEDB_NOPROVIDER error to return the name of the provider we failed to find. This will appear in the RC0 release of SQL 2008.
SSIS Error Code DTS_E_OLEDB_NOPROVIDER_ERROR. The requested OLE DB provider SQLNCLI.1 is not registered. Error code: 0x0000000
This should help in debugging issues related to connection string upgrades.
