When there are millions of Windows users world-wide successfully using
Windows Update, and nothing works on your particular network with Windows
Update, statistics might suggest that the problem lies with your network,
rather than with Microsoft.
You are running Websense and Netscreen, and either of those could obstruct
the correct operation of Windows Update, and the chances are that is
precisely what is happening.
The Windows Update world-wide network uses a pool of slave servers that can
change from time to time: maybe you have Websense/Netscreen configured to
allow access to last week's slave servers, and not this week's.
Some packet sniffing would show you exactly what was going on inside your
network when the HTTP requests fail.

80072f76.
