The negotiation process may be smarter now, but I know a few years back setting a router/switch port to full duplex turned off any negotiation with the connected device and any device that did not offer to negotiate was assumed to be half duplex by it's partner. Either that situation has changed or your clients are doing the wrong thing even though the result is what you want. Anyway, these days I try to leave everything on auto unless I know that even with the latest firmware/drivers it still won't work. -- Les Mikesell les@xxxxxxxxxxxxxxxx
