I have been having a lot of problems with network throughput. File copies fast one way, not the other. I've replaced hardware and drivers to no avail. I have downloaded a packet capturing program that is allowing me to eavesdrop on these cards as their arguing one way and not the other but I need help with the diagnosis. Is there some way I can post some capture files so someone can help me. This would be very helpful for me. Does anybody out there Know Packets?
