SUMMARY
For versions of the Microsoft SQL Server client-side Multiprotocol Network library prior to Microsoft Data Access Components (MDAC) version 2.1, any Multiprotocol connection requires a trusted Microsoft Windows NT connection, even a Microsoft SQL Server authenticated login. Versions of the Multiprotocol netlib included with MDAC 2.1 or later relax this requirement. If you use Multiprotocol to make a SQL Server authenticated connection from a client that has MDAC 2.1 or later installed, you no longer need a trusted connection. If you request a Windows NT authenticated login when you connect to SQL Server, you need a Windows NT trust (your Windows NT credentials must be recognized by the server) with any version of the netlib.



MORE INFORMATION
The version of SQL Server to which you connect is not relevant. The versions of the Dbmsrpcn.dll (the Multiprotocol netlib DLL) file that do not require a trusted connection for a SQL Server authenticated login have a file version of 1998.11.13.0 or later.
