I'm sorry that my comment wasn't very clear, both of my 7200's HAVE the clock hardware (according to the til). A 20 mhz can right next to the ethernet chip and the 50 pin scsi connector. So... the problems still appear to be in the drivers.. When I get some time I'm going to move from a switch to a hub and put tcpdump on another machine to see what's up when the mace stops working. In previous testing it appeared that the 7200 was ignoring the INCOMING packets. We'll see... Bob -- Robert E.
