Windows VDA – KMS’s problem – Resetting rearm count

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

10-19-2016-10-54-11-am

Mount a vdisk in maintenance’s mode

10-19-2016-11-08-10-am

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.

10-19-2016-11-12-36-am

Now unmounts the vdisk.

10-19-2016-11-16-42-am

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 🙂

 

 

 

Thanks !
