great post anyweb !
i have a question for you, but i dont think it's same topic
i have SCCM2012 SP1 & Wsus 3.0 installed on windows 2012 server, everything run smoothly.
but a few month ago, i had change my proxy server. and all serer run without proxy.
the problem is, when i change proxy settings on sccm server (i change the settings through internet option in control panel) i found that wsus proxy still use the old configuration.
i change proxy on wsus, then synchronise succeeded.
but few hour later, the proxy change again (back to old proxy setting). i change it manualy every 3 hour, and synchronise manualy.
i had change the Proxy And Account Settings on server & sites system roles -> software update point and uncheck all proxy settings for update point.
