I am having problems with Windows Update through a BM 3.9 proxy server.
There is no authentication required. I have tried all the sets the
Micro$oft recommends and still no joy. Setting the proxy in the Internet
Options and transferring into "netsh winhttp" does not work. The same
computer (a notebook) taken outside the network and with proxy server reset
to "none" works fine.

I have other computers that do not update as well, but this is my current
guinea pig. Any ideas?
