[Winpcap-users] Capturing packets for a certain time

[ceo at triplebit.com]

Hi all,
My p2p fail to communicate when the transmiter runs under some Windows Vista(just in one environment, in another Vista machine it works fine). In the WireShark I see that all the packets appear with CheckSum error with the folowing hint:
UDP Checksum Offload
When I disable the checksum option in the network card the errors persists and so does the indication in the pakets.
I guise that the error source is different but can't figure it out.
Can someone advise please?
Regards
I. lesher
