Testing of NDIS Miniport driver

I am new to Window driver development.

This is quite a basic question, I have. Hoping someone would be kind enough to guide me in understanding the working of a NDIS miniport driver (from Microsoft WDK samples).

I have installed two instances of this driver. Also I have WinDbg tools and Wireshark installed.

Please let me know how to test this driver and debug it to understand the working.

Thanks,

Best regards,
Denny Mathew
