Why is networking so slow?

If I click on "Network" it takes about 4 or 5 minutes to actually update &
show all the PC's.
A file that took 5 minutes to D/L from the Internet (~500mb) takes an hour
to copy to another machine over a 100 MB network.

All non-Vista machines on the network are fast & do not have this problem.

I'm not sure why, but I experience the same slowness. Many users
have reported the same thing, too. It is quite aggravating.

I took this from an earlier post

It could be that your networking equipment is having a problems with Vista's
new TCP/IP stack. Try typing the following at a command prompt with admin
priviledges:

netsh interface tcp set global autotuninglevel=off

to turn it back on just change the off to on. See if maybe this helps. I
had problems with my wireless router until they
came out with updated firmware, so I had to do the above to get it to work
properly.

On the server or the Vista machine?
