[Winpcap-users] Winpcap stops forwarding packets

[Lasse Thorbro-Steenberg]

Hi,

I wasn't forwarded your response on the mailing list, so I a did a cut and
paste from the digest.

Your card is Intel based and the HP card I use is Broadcom based. So I dont
think this is a card issue?!
A process hangs somewhere that requires the network card to be
disabled/enabled to get going again.

It looks like it has been a while since winpcap was updated. Is it possible
to have a look at the source code ?

For what it?s worth, we found the same issue on Intel?s 82574L adapter.
Even after considerable go-around with Intel we couldn?t get the interface
to be reliable.  We Installed slot-based cards to replace the on-board NIC.
