Having an odd issue when restoring a vmware VM (Windows 2012 r2). An application on the VM ties its license to the MAC address, so on completion of the restore, I manually change the MAC address back to the original MAC.
My problem is that Windows Activation is lost. When trying to run slmgr /ato it errors out with 0xC004F074 The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted.
I have already tried running slmgr /skms to specify the name of the kms host, and I have confirmed I can telnet to the KMS host on 1688.
The original VM is working fine and can activate normally.
Any advise is appreciated.
I suspect the restored VM has been kicked out off the AD.
This happens when the hosts AD object and AD object time staps diffrence get too large.
Once re-joined to the AD a KMS activation should be possible.
