title: Visual Studio 2015 Community License update fails in Samba NT4 Domain due to proxy/firewall
body: <p>First off, I read all other Questions, that relate to this, I did an extensive google search on this topic and could not get a working answer. </p>
  
  <p>I installed the Community Version of Visual Studio 2015 in mid November and been using it since then. After finishing my project, I went back to pen and paper for new formulas and noe came back to implement all those neat things.</p>
  
  <p>Now it says, that my trial license has expired and should be renewed. I already read, I should use my MicrosoftAccount to do that, and proceeded by doing that. 
  <a href="https://i.stack.imgur.com/kGtHR.png" rel="nofollow noreferrer">Now this happened</a></p>
  
  <p>It says, I should check firewall and prxoy settings and I read about contactiong the administrator. So that, what I did, but he says, there is no proxy, no block by firewall or anything else. 
  When running VS as administrator (after entering my credentials) I can create new projects and debug existing ones, so no problem there. However I can not use the program as normal user. </p>
  
  <p>I read somewhere here to try repair it via systemcontrol, but that did not work either. 
  Does anyone has a solution?</p>
  
  <p>In addition: There is also no "Enter License Key here" field, so that is also not an option. </p>
