I'm trying to access a SharePoint site I was previously able to successfully access a few weeks back with IE 8.0.7601.17514. Now when I try to access it, I am prompted for my username/password 3 times and then a blank screen is displayed with "Done" in the status bar. This was tested on three different laptops, from two different locations with the same results (also received the same results when trying Firefox or Chrome). I changed my browser settings with no luck. Any suggestions?
