Hi Rob: Thank you for this help. Thanks also to all others who replied this evening. I just came home and it is late so I will pursue all suggestions tomorrow evening. My gut sense is that it is the nic setup - at first I thought it might be my router (and maybe it is part of the problem but I have operated 3 different machines through it and networked them in the past so am starting to get pretty comfortable with it). But tomorrow I will start by checking my cabling carefully - though the same machine if booted into Win98 works flawlessly so I doubt that the problem is cabling or flaky nic. The nic is a 3com 3509 which seems to be well supported. Auto negotiation - that sounds plausible - esp. since sometimes files do get through but painfully slowly. Lowering the MTU setting shouldn't hurt...? To all - thanks again, I will respond further after playing tomorrow.
