Then you can rule out that it is hardware related, might want to inspect the settings of device manger or other network related settings on the pc's and compare that.

what is the connection sync speed you get on the computer that caps at 100? is it 1 gbps or 100 mbps?
(in addapter settings right click on the ethernet connection and select status)

Is the problem pc plugged directly into the router or does it go through a patch panel or something? Can you verify on the advanced adapter settings that "speed" or "speed & duplex" are set to "auto negotiate"? generally this would not have gotten changed, but you never know
