I've recently installed the Software Update Service (SUS)
on my Windows 2000 server, however when I came to
configure the client I had some problems. In the
deployment white paper it explains what registry key you
need to edit to direct Windows Update to your local SUS
server, but the key doesn't exist
(HKEY_LOCAL_MACHINE\SOFTWARE\POLICIES\MICROSOFT\WI NDOWS\WI
NDOWSUPDATE\AU)! The closest one I could find
was "HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CUR RENT
VERSION\WINDOWSUPDATE\AUTOUPDATE" which didn't appear to
work.

Can anybody shed some light on what regedit I need to
perform to get SUS to work?

Those Keys have to be created either manually or through
the MMC, I am not sure of the appropriate snap in. I
believe it has to be downloaded. The keys effectively set
local policy for that machine.
