title: User CALs shared over multiple servers
body: <p>Take following scenario:</p>
  
  <p>In a company, there's a domain "COMPANY", where the following servers are hosted:</p>
  
  <ul>
  <li>2 x Windows Server 2008 R2 Enterprise (DC)</li>
  <li>5 x Windows Server 2008 R2 Standard (non-DC)</li>
  <li>5 x Windows Server 2008 Standard (non-DC)</li>
  <li>1 x Windows Server 2012 Standard (non-DC)</li>
  </ul>
  
  <p>In the company there are 500 devices and a physical head count of 250 users.</p>
  
  <p>Because there are more employees than devices, it's logical to use User CALs instead of Device CALs. So we buy 250 User CALs.</p>
  
  <p>Now, 2 questions:</p>
  
  <ul>
  <li>is it true that those 250 User CALs are valid for all Windows Servers of the same version (2008 R2)? It doesn't matter if it's a different edition or not (Enterprise/Standard)?</li>
  <li>For the 2008 Std and 2012 Std, I'd have to buy each 250 separate User CALs? (assuming all employees have direct or indirect access to the server).</li>
  </ul>
  
  <p>I find the documentation of Microsoft concerning licensing incredibly unclear, and I'd like to make sure.</p>
