I'll comment on this one since it was my start. But in another e-mail You noted that all the yellow lights are solid. On my Switch in my house (4 comps) the DX/Collision light is always lit even when only one box is connected. (regardless of which box it is.) Seems to be the nature of some Switches. (The manual says a solid light is ok a flashing one is a sign of collisions.) You might try unplugging one box at a time (start with the Micron) and see if the net picks up speed. If not plug it in and go to the next box. (unplug on the hub that way you eliminate the wire as well and it's less crawling on the floor.) Do a TCP Dump on the network when nothing is going on expect turned on boxes. If you see a lot of traffic from one box... you've found your victim. Traffic should be minimal. I believe ME and 2000 still pole the system periodically to say "I'm here" that should be all the traffic you have.
