The "-HD" = Half duplex = kiss of death for speed. This usually
indicates either a bad cable or an incorrectly configured network
box. We'd had problems with DEC/Compaq AlphaStations in this regard.
The solution was generally to configure your network box and/or workstation
to 100baseT/Full and *don't* let it autonegotiate.
Hope this helps
