There I was, happy, with my fresh install of Windows Server 2016 Tech preview 5 and an equally fresh copy of Visual Studio 2015 Update 3. That happiness was taken away from me when I tried to checkout some code from Visual Studio Online where I received the error “TF31003: Either you have not entered the necessary credentials”.
"TF31003: Either you have not entered the necessary credentials or your user account does not have permission to connect to the Team Foundation Server at https://... Ask your server administrator to add the appropriate permissions to your account."
The thing was that I never entered any credentials at all. It just blocked me out from start which made me blame Internet Explorer that I never even opened on this pure box, I mean why would I?
First thing I tried was to open the VSTS-portal and login, i.e. https://www.visualstudio.com/ and press login where I got bricked by IE telling me my cookie settings was all wrong.

When I checked the settings it all seemed good.
Internet Options > Privacy > Advanced
What I discovered was that the settings displayed was not the ones used, I'm not going into detail here but to fix it simply change the values.
Press OK + OK and close Internet Explorer. Open IE once again and set the settings back as they were, or like this
Press OK + OK and possibly restart IE once again.
All good, I'm happy again.
Cheers
