A client of mine called me on friday stating that she is now unable to view certain websites correctly. I connected to her machine and found that she can view search results fine via google however when she selects a site i.e. "bbc" and the page loads its as if something is blocking the content (see below image). The issue seems to be network wide as the results are the same via the sbs server. I have tried a multiple browsers as well as restarting the server which did not help, i also flushed the dns cache on the sever which made no difference.
