Have a small network of windows computers and a few servers. The boss wants to be able to watch tv using diynetwork.com or hgtv.com (Same TV provider, different site). If you go to watch live TV and click the play icon that is overlayed the video or click the "sign in to your provider" button at the top right, nothing happens at all. This happens on all workstations and servers on the network. No other DNS or internet issues exist. I've tried Edge, IE, Chrome, and Firefox and all have the same issue. I've put chrome in guest mode (Shift+Ctrl+N), and still has the issue. I've checked security settings, java, activex, compatibility view, cleared temporary files. I've temporarily disabled all security on the Sonicwall and I've checked group policy but nothing has worked. Any ideas?
