Hello, I have installed and setup the SCCM 2012 Rc, and implemented the Software Update Point togheter with WSUS. Since we do not have direct connection to internet, I have to setup the proxy server. But I need to connect to the proxy with another user then a domain user and with basic authenticaton . I cannot seems to setup "The software update Point proxy server account " as a non-domain user and their is no checkbox to select basic authentication in Sccm 2012 console. In SCCM 2007 , I adapted the sitectrl.ct0 file with these settings, but how can I do that in Sccm 2012 ? Thx
