Not much I can help with here, but I know you can get the Logitech MX5000 to work in Win2k. I have the same keyboard/mouse and I'm using Win2k. If you go the the Logitech site and check under MX5000, it only lists driver/software for XP/XP64, but if you go to MX1000 mouse, you'll find software also for Win2k. But it will not work with KVM switches (at least I haven't found any it will work with).
