In these cases locking the switch port to 100 Half has resulted in a dramatic speed-up in my experience. I can't tell you offhand which cards these were, but give it a try. -Mitch >It is on a switch ! Actually everything is set on auto on both sides so >they should be detecting the speed by themselves.
