I don’t speak German but see the post ‘Cubase iC Pro official video tutorial’ and read my response if you are having problems connecting the iC Pro.
If you cannot connect, follow my steps and you will. And remember that the last step is running the ‘Network Diagnostic in Win7’. I have looked all over the internet and there is no answer as to why Win7 will not connect to the Home Group without running the diagnostic tool. I need to call MS about this.
