Is the switch managed or unmanaged? You can't set full duplex on an unmanaged switch, it is always in auto. If you have an unmanaged switch you MUST set the computers to auto or to half. Setting them to full will most definitely cause problems. The auto-negotiation specification says a port set to auto must choose half if the other end is not set to auto. This is an extremely common misunderstanding. -Mitch
