The reason is that auto mode uses fast link pulses in order to negotiate speed and duplex settings. If the client is hard coded to 100 full, there are no fast link pulses going between the client and switch. The switch decides that nothing else will do in our technologically advanced world besides 'half duplex' - leading to duplex mismatch problems beween the workstation and the switch.
