[squid-users] Solved :: Squid + Windowsupdate Problems

  A big thanks to Tom Earl who wrote to me and explained part of the
problem.

For our network, we only had problems with v5.windowsupdate.com - the
windows update for Windows XP.
If that matches your symptoms, this is what worked for us --
1.  Check to make sure the WinHTTP is using a proxy.
In Windows2000, the update system picks up the proxy configuration from
IE settings.  This is no longer true in XP.
At the XP command line, type "proxycfg".  This will tell you if the XP
box is using a proxy.  If you want to import the settings from IE, type
"proxycfg -u".
2.  The ActiveX control that actually downloads the update is too stupid
to authenticate.   So, in squid.conf you have add the lines:
acl windowsupdate dstdomain .windowsupdate.com
http_access allow windowsupdate

  It seems it wasn't a Squid problem after all. "proxycfg -u" fixed our 
problems.
