If you have more than 50 clients, we recommend that you have at least two KMS hosts in case one of your KMS hosts becomes unavailable. PrerequisitesĪ single KMS host can support an unlimited number of KMS clients. To learn more about KMS and the initial planning considerations, see Key Management Services (KMS) activation planning. This article walks you through the steps you need to create a KMS host. The KMS clients that a KMS host can activate are dependent on the host key used to activate the KMS host. KMS clients connect to a KMS server, called the KMS host, for activation. KMS uses a client-server model to active Windows clients and is used for volume activation on your local network.
