SYMPTOMS

Installing Microsoft Data Access Components MDAC 2.6 RTM on Windows 2000 or Windows NT 4.0 Professional, Server, or Advanced Server-based computers prevents error text description from being returned from the Microsoft OLE DB Provider for SQL Server (SQLOLEDB). The Microsoft OLE DB Provider for ODBC (MSDASQL) is not affected.

CAUSE

Localization issues cause this bug. If the system locale settings are not set to match the user locale setting for non-United States locale settings, the SQLOLEDB Provider returns an error when it encounters one, but the description text associated with the error is not returned.
