Silly question - how are the switch ports configured? I'd try toggling it from whatever it it is now. We've seen some similar sounding problems with Intel NICs and Cisco switches where either auto or forced port settings will cause extremely slow transfers without causing any errors on either end. It's card/port specific, too, as we've seen cases where allegedly identical hardware must be configured as the opposite of its "twin". Chris
