Hi Pedro.

Can you send me a sample of the winpcap_debug.txt file of a failing machine?

Have a nice day
GV

Hi Paul

I have about 100k users using Winpcap as a low-level lib for my high level
app., every now and then I receive complaints from them about not being
able to detect their network adapters. The behaviour is similar to yours, in
that PGANames(.) returns False/empty list.
I have been asking for them to use the debug version of the Packet.dll and
get me the generated winpcap_debug.txt , tcpip.reg, services.reg ,
npf.reg , adapters.reg.
I do get some replies with these files, but I don't want to bother the
Winpcap developers; being a "mediation device" between my end-users and
Winpcap development, it's hard 4 me to reproduce it or answer questions on
the machine setup.

Hopefully, you will be able to provide + info to Gianluca so we can fix this
trouble for g00d.
I can provide some samples of the above files also.

Hello,

I am having a problem running winpcap on my Thinkpad T42.

My system is a IBM Thinkpad T42 with:
WinXP Pro SP2
Intel PRO/1000 MT
Intel PRO/Wireless 2200BG
WinpCap 3.1 beta4 (also tried with 3.0 alpha3, which works with this app
on 
other XP installs)

I have an application that utilizes packet.dll to loop back packets. It
gets 
an empty list when calling PacketGetAdapterNames(). Reading the FAQ, I
tested with windump. I get strange results. Every other time it returns
adapter info.

Running 'windump -D' in a cmd shell gives me this:

F:\>WinDump -D
WinDump: PacketGetAdapterNames: There are no more files.

F:\>WinDump -D
1.\Device\NPF_GenericNdisWanAdapter (Generic NdisWan adapter)
2.\Device\NPF_{3336EC4C-31DB-4DCD-8E4C-340B968FFB09} (Intel(R) PRO/1000 MT
Mobil
e Connection (Microsoft's Packet Scheduler) )
3.\Device\NPF_{C7802EB6-B280-46AA-8CBC-BBEA3D97A353} (NOC Extranet Access
Adapte
r (Microsoft's Packet Scheduler) )
4.\Device\NPF_{83160726-7FD8-4181-BA3F-B4F3DCC6A221} (Intel(R)
PRO/Wireless 
2200
BG Network Connection (Microsoft's Packet Scheduler) )

F:\>WinDump -D
WinDump: PacketGetAdapterNames: There are no more files.

Etc.etc....

Currently the PRO/1000 interface is the only one enabled. I have disabled
firewall and any virus detectors.

Any idea?

Thanks,
Paul
