vamt activate through active directory server 2019 error Product key not available

Copper Contributor


I setup a new VAMT server on a Server 2019. Installed the volume-kms-key on the server and add it in VAMT. I put the KMS key for Win10 LTSB, Win10 LTSC, Office 2016 and Server 2019 of via Volume activation tools in the active directory. After that i installed the KMS client key for the server 2019. Now i try to activate a license on a server 2019 with the option automaticaly select a kms client key (GVLK). It return with an error "Product key not available".

The strange thing is that when i select manualy the same kms client key (GVLK) for server 2019 and after that i select activate license it works. On the info of the server it says Volume activation methode: Active directory activation and AD activation object: Windows(R) Operating System, VOLUME_KMS_WS19 channel what is the right one.


How can i get a direct license activation through active directory like for my windows 10 LTSB workstations.
