Somehow both NIC cards had their "Link Speed" property set to 10 Mbps. Raising it to 100 Mbps almost fixed it. Now XP-to-Vista transfers are averaging 75 Mbps. But, Vista-to-XP transfers are maxing at 85 Mbps, but averaging only 25 Mbps. Lots of what I'd call "pulsing" on and off. So, I'm getting close. Although I've done a fair amount of hacking on the OS over the years, never touched TCP.sys. Can you provide a detail or two more on what you're suggesting.

I've been having some speed problems: 1. Vista gets only 8 Mbps at www.speakeasy.net/speedtest, but XP (on a different computer, same router) gets twice that: 16 Mbps. 2. Transfers between machines through a router run at 8 Mbps. I'd expect ten times that. I've uninstalled & turned off all firewalls, virus programs, etc. Looking in the device manager, I see over 20 identical ISATAPS. What reading I just did doesn't reveal to me why they'd be there. I suppose I can remove all but one of them, but I hate to start messing with this until I know what's going on. Computer is a Dell Latitude D-820 w/ Broadcom NeXtreme 57xx Gigabit controller. D-Link DI-604. Anyone have any suggestions on how to proceed? TIA, Tom
