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.
- Add a Windows Server 2012 R2 HotFix, which can be found here
- Reboot server
- Add a SRV record to any of your primary domain controllers
- Wait for all domains to synchronize DNS information
- Install the correct KMS host server key
- You’ll need to go to licensing.microsoft.com and download the proper KMS host server key
- 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
- Use the following commands, in an elevated CLI, to register and activate the KMS host server key
- SLMGR /ipk CCCCC-XXXXX-PPPPP-KKKKK-MMMMM
- SLMGR /ato
- 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 below
- These steps will allow you to install the proper host server key and allow your Windows 10 clients to get licensed.
