I'm having a very strange problem. I have 2 computers (Mavericks 10.9.2) that work fine with Access, but on one I cannot login -- it says I don't have an internet connection (which I do). When I try to go to access.parallels.com in a browser on that computer, it says there is no such server, while the other computers (and my iPad) have no problem. I've tried everything I can think of: 1. reinstall Mavericks; 2. connect through ethernet; 3. use three different browsers; 4. reset DNS cache and internet connection (network); 5. delete all cookies. Even when I log on the problematic Mac as another user, it does not connect. BUT it works fine when I connect through Windows 8 running in Parallels Desktop. Does anyone know what is going on? There are no other websites or programs I use that have this problem. I do not use a firewall.
