Even though you can make it work, I believe in doing so you will be running afoul of the WSUS license agreement if it's not a corporate LAN/Domain. I don't have the text of it in front of me, but I remember this issue coming up on <nntp://microsoft.public.windows.server.update_services> Since automating clients to use wsus requires either a registry or local/group policy change on the clients, you would have to find some way of manipulating this facet as well. I would say the best course is to contact the wsus/mu team via the above mentioned newsgroup and see if they'll become more cache friendly with a future version of wsus. The squid trick seems ideal if only you could be assured of having the latest files. ~JasonG --
