Also, try disabling network autotuning (run the following with
Administrative priveleges):

netsh int tcp set global autotuninglevel=disabled

and then reboot. I have had MAJOR issues between Vista and R2 boxes,
but not with regular 2003 boxes. This is fixed with SP1, but since
SP1 isn't out yet, the autotuninglevel (+ maybe the rss) workaround is
the trick.

The RSS command is:

netsth int tcp set global rss=disabled
