I have Vista ultimate _without_ SP1 and the above works. Do I have to
input the command every session Conor? Just copied an 800 meg video
file to my NAS in around two minutes as opposed to the usual 15 or so
it was taking before. I always wondered why my wife's XP machine could
copy a file from the NAS so much faster than I could.

Many thanks for the heads up!
