Vista has network "optimizations" which work very well when the client and
server both have relatively recent network drivers, but can perform very
poorly with older network drivers. It could be that these optimizations are
counter-productive on an older 10 mbit network, since the optimizations
assume reasonably modern switches.
You can disable these "enhancements" to see if it makes a difference. I
don't remember the exact syntax but you can look for commands like this:
netsh int tcp show global
and
netsh int tcp set global
The parameters of interest are receive-side scaling and chimney offload.
