I have tried using the FQDN and the IP Address of the KMS Server. Using the command 'slmgr.vbs /skms my-kms-server', I configured the KMS server. From the Server 2019 server, I am not able to Activate Windows. The new Server 2019 server is on the same subnet as the KMS Server. I also have Office 2016 and Office 2010 Product Keys installed and machines successfully activate to this KMS Server. We have many Win 10, Win 7, Server 2008R2, Server 2012, and Server 2016 machines successfully using this KMS server. The KMS server is running Windows Server 2016. On our KMS Server, I added the Server 2019 Product Key using the Volume Activation Management Tool. Here are the steps we have done: From the Microsoft Volume License Service Center webpage, we retrieved the Server 2019 KMS Product Key. I have also created another new Windows Server 2019 machine and it is not able to activate using our KMS, so it may not be specific to the one VM. Hello Experts! I am trying to Activate a new Windows Server 2019 server against our KMS Server.
