To make this basic as possible.
I have two XP computers on one switch.
They are on .100 subnet
When I ping a machine on the .110 subnet one pc gets <1ms and the other pc gets 50 ms.
I have concluded it has something to do with the pc because I swapped ports and get the same results multiple times.
I need suggestions on how to test why one machine is fast and the other machine is slow.
They have the same gateway so they are using the same routes. (which works for one.)
