Hi!! Windows Update really has problems authenticating to squid, so you need to use some rules in order to get it working. The rules that we are using are the following: acl WindowsUpdateSites dstdomain .windowsupdate.com .windowsupdate.microsoft.com .update.microsoft.com Then, before the http_access rule that requires user authentication, use this one http_access allow WindowsUpdateSites Regards, Carlos. 2005/8/25, Matt Ashfield <mda@xxxxxx>: > Hi All > > A bit off topic, but I've had some users complain that they are having > problems when going to windowsupdate and it tries to validate their copy of > windows.
