We have an HP929-20. It had one lan card installed initialy in the processor chassis. We added an expansion chassis and two adition lan cards. All three are the same, the number escapes me at the moment, but they are 100t's. The two new ones were configured full duplex, from what I can tell from the hub they are connected to 1 is full, the other is 1/2 duplex. Any hints? The machine has been rebooted twice since the cards were instaled, The CE helped us set them up, so the two new ones are identical. Frank Girard J.Baker Inc [log in to unmask]
