Hi,

I have attempted to install/run WinPcap & Ethereal on a server, but it
does not report any network cards back.

I have installed WinPcap 3.0 Alpha 2 and Ethereal(0.9.6) on the server.
There was no previous versions of WinPcap on the server. After starting
Ethereal I noticed that there was no network devices listed.

I opened up a command prompt and tried to manually start the NPF service
using npf_mgm -s
This returns the following error message:

Error Starting Service NPF:%1 is not a valid Win32 application

Thereafter I rebooted the server and tried manually starting the NPF
service again, but it still did not work. I can happily
install/uninstall the NPF service using npf_mgm, but I cannot start the
NPF service.

Is this a known problem ? I get the impression that a few similar issues
have been logged recently:

        Problem with detecting adapters <msg00767.html>, alex 
        Netgroup Packet Filter wont start <msg00764.html>, Anthony Clark


I have also just now tried this with the newest WinPcap 3.0 Alpha 4,
rebooting after installation of the new version. I still get the same
problem: the NPF service does not want to start. I have been logged in
as Administrator on the server.

There is something else I also find puzzling - when I look in the
Service Control Panel for the NPF service, it is not listed, even though
I can attempt to start it from the command line at such time.

The server spec is:

Dell Poweredge 2650 (Single CPU P4 2.4 GHz) with Win2000 Server SP2 OS
and 2 x Broadcom Gigabit Ethernet Cards 
(on board the motherboard)

Does anyone know of a workaround or possible solution for this problem ?
Is there anything else I can try ? I have installed and used WinPcap on
at least 5 other PC's/servers with no problems at all.

Thanks for your assistance

Regards

Jaco de Wet
