+ Have added WSUS Role (with WID) on WS 2012 R2 Essentials
+ Have disabled IE's ESC on Server so the IE on the server is definitely connecting to and browsing the Internet
+ Have only low bandwith of 2 MBit available to connect to the Internet
+ Pushed "Start Connecting" within the WSUS Configuration Wizard to download update information from MSFT Update to configure WSUS
+ Here the wizard starts and starts and starts for hours ... the running green bar circles and circles and circles ...
==>Seems to me that WSUS isn't able to find/connect to the upstream Server of MSFT update? Any good idea/hint how to proceed appreciated!
