Windows 10 Licensing On A Windows Server 2012 R2

Recently I began to get ready for Windows 10, and part of that process was to get our licensing servers up to date. Since I was getting multiple answers on Microsoft TechNet forums, I decided to open a call with Microsoft Support and get a definitive answer – all information below has been confirmed with Microsoft.

First, Windows Server 2008 R2 will be able to provide licenses for your Windows 10 fleet, with a catch. Microsoft will be deploying a Hotfix for Windows Server 2008 R2 in a month or two, maybe a bit longer, so if your organization can wait, then just hold on tight.

 
Note: Windows Server 2008 is not supported for Windows 10 licensing, this was made clear on my call to Microsoft Support!
 
After installing the Volume Activation feature, the following must be done to prepare Windows Server 2012 R2 to licensing Windows 10 clients.
  1. Add a Windows Server 2012 R2 HotFix, which can be found here
    1. Reboot server
  2. Add a SRV record to any of your primary domain controllers
    New SRV Record
  3. Wait for all domains to synchronize DNS information
  4. Install the correct KMS host server key
    1. You’ll need to go to licensing.microsoft.com and download the proper KMS host server key
    2. For Windows 10 licensing on a Windows Server 2012 R2 server, we’ll need the following key: Windows Srv 2012R2 DataCtr/Std KMS for Windows 10
    3. Use the following commands, in an elevated CLI, to register and activate the KMS host server key
      1. SLMGR /ipk CCCCC-XXXXX-PPPPP-KKKKK-MMMMM
      2. SLMGR /ato
  5. After allowing all DCs to synchronize, we’re going to run a command to make sure that the new KMS server is ready to authenticate clients
    a. nslookup -type=srv _vlmcs._tcp
    b. Copy and paste the command in step 5a onto a desktop and results should be as shown in the screenshot belowNslookup for SRV
  6. These steps will allow you to install the proper host server key and allow your Windows 10 clients to get licensed.
