I would probably recommend setting up the free SUS server which would have direct or regular proxy access to the official servers, and use group policys to direct all your clients to your inhouse server. http://www.microsoft.com/windowsserversystem/sus/default.mspx ooo just noticed they're doing an update to it called WUS. Hope its good! ;)

We had similar problems with WinXP clients trying to get updates both automatically and manually from Windows Update (v5, but be had intermittent problems with automatic updates on win2k - v4.windowsupdate...). Turns out M$ can't figure out how to implement authenticated proxy requests from the client to a proxy for Windows Update. I found a M$ knowledge-base article about it and the suggestion was to allow all requests to "*windowsupdate.microsoft.com" to be done without proxy authentication. The way you do this in squid is to put an ACL to allow requests to windows update BEFORE the ACL that requires authentication. I'm offline ATM, but the I can send you the relevant bits from our squid.conf if you like. Cheers, James This message is confidential. You should not copy it or disclose its contents to anyone.
