Ah, that's good to know! I rather like Netgear's switches!

So, same topology I'm having problems with.

I've left everything at the default (auto-negotiate) settings. I
remember reading that not using auto-negotiate with GBE is a no-no.

Well, the switch is all GBE (as you probably know), but only the link
to the server is running at 1Gb/sec; the Sun Ray links are (of course)
running at 100Mb/sec.

Netstat -i shows no errors:

Interesting. I am using the Nvidia chip. Do you think it would be
worth swapping the interface even though nge0 has no errors?

It's CAT 5e rather than CAT 6, but given the relative;y short
length, I don't think it's a problem (but I will bare it in
mind).
