The full text of this error message resembles the following:
The Software Protection Service reported that the computer could not be activated. The count reported by your Key Management Service (KMS) is insufficient. Please contact your system administrator.
Possible cause
The count on the KMS host is not high enough. For Windows Server, the KMS count must be greater than or equal to 5. For Windows (client), the KMS count must be greater than or equal to 25.
Resolution
Before you can use KMS to activate Windows, you must have more computers in the KMS pool. To obtain the current count on the KMS host, run Slmgr.vbs /dli.
0xC004F039 The Key Management Service (KMS) is not enabled
