Outstanding question and answer. I really appreciate your careful description. I had the same problem. In my case the problem was that I was accessing Report Builder from a machine connected to my home office by VPN. I guess because I was outside of the Windows network of the home office, RB couldn't authenticate me. Working with a Remote Desktop connected to a machine at the office allowed me to side-step the problem. Your and @RichShealer's answers reminded me that when running the reports from the browser, they're being served up by an inside server machine. This is not the case when running RB, a desktop app.
