How to understand the internal working of NDIS Miniport driver

I am new to Window driver development.

I am trying to understand the working of a NDIS miniport driver (from Microsoft WDK samples). Especially, to understand the packet flow.

As per numerous sources, I have seen suggestions of installing two instances of NDIS miniport driver and proceed from there. However, I am unable to continue from there, as there is only vague info. Please advise - Especially on how to attach a Windows Debugger Tool to an instance of the driver and to see the callbacks being called on sent/receive packets.

My platform: Windows 7 x64 with debug mode set (Debugging Setup: Single Computer).

There is a similar question. But no info about how to debug the driver: NDIS and miniport driver

Solution

  • You can't debug on the same machine in which you are running the driver, you need to use remote machine, that could be a "Real" one or as done usually a VirtualMachine.

    Here how to setup a Windows Kernel Debugging environment with a Virtual Machine:
