Hi everyone !
Today I will talk about a problem I seen often if you manage a big streamed virtual desktop’s group. The loss of the KMS’s activation, not due to a Windows’s problem, but a problem with the streaming software that does not generate unique KMS’s key.
An example of bad health on the KMS’s host; …
Open the Provisioning Services Console
Mount a vdisk in maintenance’s mode
Use regedit, click HKLM->Load Hive, and open in the new attached partition the SYSTEM’s file.
Give it a temporary name
Naviguate to HKLM\WPA, and erase that folder completely.
Now unmounts the vdisk.
After load the virtual machine up.
Issue that command; slmgr /rearm, and close the VM.
Now watch your KMs’s host event log, unique ID should be displayed 🙂
Now it’s finished 🙂
