That means it's probably a WinPcap problem, not an Ethereal problem or a
WinDump problem.

	http://www.ethereal.com/faq.html#q4.12

is the FAQ for

and gives details on how to report WinPcap problems.

Ask the WinPcap people.

The diagnostic message is what WinPcap gives us; that's all we can
display.

The "Submitting Bugs" section of the WinPcap support page, to which the
FAQ in question refers, gives information on how to get more detailed
information to send to the WinPcap developers, by downloading a special
debugging version of WinDump and running it.
