  Does the same hotfix also apply if we're using Active Directory Based Activation instead of KMS?

  Thank you Pavel for your comment, installing the VAMT from Windows 10 ADK did the trick for us. But we had troubles finding the ADK, Microsoft has decided to remove the download...
  
  Windows Assessment and Deployment Kit (Windows ADK) for Windows 10 Technical Preview

  but in the next page we found the file:
  
  At the bottom of the next page:

  Where it says "Download the Windows ADK for Windows 10"

  @Billy and Tony, at the moment, there is no ETA of when the update for a Windows Server 2008 R2 KMS is coming besides what's documented inhttps://technet.microsoft.com/library/jj612867.aspx as DerkaDerk pointed out. I'll make sure to update the blog post as soon as it's available. Thx. Yong
