[Winpcap-users] WinPCap and VNC/PCAnywhere

[Loris Degioanni]

The WinPcap NPF driver is a standard NDIS protocol driver, and receives 
the packets from the network adapters by means of standard calls to the 
NDIS inerface.
Some applications can break this interface, both deliberately (e.g. 
firewalls or packet filters, usually implemented as NDIS intermediate 
drivers, and thus sitting underneath NPF) and inadvertently (mostly 
buggy drivers that use kernel level hacks, not considering that there 
could be other protocols besides TCP/IP).

In Either cases, we don't have many weapons besides suggesting our users 
to disable or remove (sometimes disabling is not enough) these applications.
