Set the MTU to something > 1500 (like 9000) and see if you can still communicate via the switch. I don't know if the NT drivers support jumbo frames. I know the FreeBSD drivers do. If you can set it to 9000 and it does work via the switch, try linking the machines directly to rule out brokenness in the NT driver. > And would the numbers (132 Mbit/s) be tied to the OS (NT) or the > driver ? It is hard to say. It could be either.
