Re: .dll file not found

["Rob Nicholls" <robert () everythingeverything co uk>]

Hi Adriano,

I think what I'm about to say is correct... nmap.exe uses packet.dll (a
WinPcap file), which depends on wanpacket.dll (a WinPcap file), which
depends on NPPTools.dll (a Microsoft Corporation file). This last dll is
not present on Windows 9x or Windows Vista (I believe).

Vista was properly supported as of WinPcap 4.0 (WinPcap 3.1 should work,
but with "limited functionality" and "known limitations") and I believe
that's when NPPTools.dll was dropped (actually, I think it was dropped in
WinPcap 4.0beta3, at the same time as support for 9x was dropped?).

So it's probably not a bug in umit or nmap, and as Vista isn't properly
supported by WinPcap before 4.0 I don't think it's their fault either.
It's probably just a quirk of Grant using nmap on Vista with - presumably
- an outdated version of WinPcap that was never really designed to work on
Vista (Vista Beta1 was released less than two weeks before WinPcap 3.1),
and I suspect upgrading to WinPcap 4.x would solve the problem.

I also suspect Gianluca will quickly correct me if I'm wrong ;)

I'd strongly recommend anyone using WinPcap on Vista to make sure they're
running 4.0.1 (or higher).
