Windows Update via Proxy

[stun]

We have a Windows XP Professional Client SP1 and would like to proceed to automatic updates. The internet connection is granted via a proxy on port 8080. The connection to the update site is correct, but when downloading the updates, the svchost.exe connects directly to the public ip on port 80. As we do and will not grant this rights to the clients, the updates cannot be executed (blocked by our firewall). I was not able to locate the problem, on other XP clients, the svchost.exe connects correctly through the proxy while downloading the patchs and update packages. Any idea where I have to search? Thanks for help.

I would implement a SUS (Soon to be WUS) server, but see this discussion:

SUS will actually not be implemented; we are waiting for next release. Thanks for the link; unfortunately, the error doesn't happen with automatic updates but manual update....

I inplemented solution described in 'Windows Proxy Autodiscovery' section with WUAU autoconfig script on intranet server and local DNS (it is universal solution). It works for me without problems about half a year. I dont remember where I got this text, but many thanks to author
