Hi Guys,
Correct me if I’m wrong, I believe windows update uses WinHTTP, not HTTP proxy server in IE. Endpoint Protection Update leverage windows update, so it should uses WinHTTP, but I found smsexec .exe uses HTTP proxy server in IE with the local system account when updating.
I was having the same problem as http://scug.be/valerie/2012/11/20/config-manager-software-updates-download-failed/ just curious know if my statement are correct
