Why do I get error message "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection"

This error usually indicates that SQLServer (or MSDE) is configured to use Windows Authentication. If you want to use a SQL login, you will need to enable SQL Authentication (mixed mode authentication). For more details refer PRB: ASP/ODBC/SQL Server Error 0x80040E4D "Login Failed for User ’(Null)’"
