Do you run WinpkFilter inside Virtual PC (guest) system? It should work fine in this environment unless you also have installed some software which conflicts with WinpkFilter drivers.
What ListAdapters does show you? Also could you specify host and guest operating systems along with version of Virtual PC?
At the moment I can only say that host system is XP Home and guest is XP Prof.
I made clean install of XP Prof and installed there our product (based on pktfilter).
No adapters were cought 🙁
That is to say the same procedure runs fine under VMWare.
Accurate adapters list I will post later, as long as VP is installed at my home
computer and now I’m in the office 🙂
