A fix for my failure to login to TFSpreview.com problems
I use a number of site collections on the Azure hosted Team Foundations Service (http://tfspreview.com); I have just solved a problem that I could not login to one of them via Visual Studio (2010, Dev11 or also TEE 11, I tried then all), but I could login to my other collections. Also I could access the collection if I logged in via a browser, just not with VS; all very good for work item management, but not much help for source code check-ins....
