If you look at TCPView's source code, it shows you how it is getting the
list of in-use ports.  There is no way to know if a firewall is blocking the
ports, though, or if they are just in use by some applications.

NDIS drivers sit as the lower levels of the socket API, and can be used to
intercept low-level socket traffic just before it reaches the network
hardware.  You can find more information about them at MSDN.
