When you run an SPX sockets application on a token ring network with miniport drivers, the loopback functionality with NWLink does not work; the SPX sockets application is not able to connect to shares on the local system.


Microsoft has confirmed this to be a problem in Windows NT version 3.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.


When you develop an NDIS 3.0 driver, half of the code is common for all NDIS drivers and the other half is specific to hardware. Miniport is an extension to the NDIS 3.0 specification which allows developers to write code specific to the hardware and merge the common interface to the NDIS wrapper.
