You cannot capture on switched networks, since the machine running winpcap does not receive other than packets to/from that host (and some other stuff, like broadcast).
On switched networks, you have to connect the capturing machine on a particular port of the switch (which is not present on all the equipments), sometimes called monitor port or similar, that receives all the packets passing through te switch. This is not a winpcap limitation, it's a feature of switched networks. GV ----- Original Message ----- From: "???
