alsosupports all the crap hardware, crap drivers and crap ACPI implementations.
He has high speed connections with 350ms ping times to the server thats
half way around the world. Windows XP, at least, did not default to
an RWIN over 64k. He needs about 300K for that link, give or take,
depending on how fast the wires are. He can go into the registry (of
the XP client) and bump is RWIN to something larger than pingtime (in
seconds) * wirespeed (in byte/sec) ... example: 0.350 ping * 700K
byte/sec = ~250K, so use 300k or 400k for TCP Recieve Window Size)
