Key Management Service migration

July 16, 2018 Leave a comment

Ran into a little problem today.  Got notified by a user that a workstation wasn’t activated.  We did all the regular stuff like verify DNS, check to make sure the KMS server is running, verify we can ping the KMS server and firewalls aren’t messing anything up.

The indication was that we logged into the workstation and entered slmgr /ato and got the error: The Key Management Service (KMS) is unavailable.  Like most problems, this was an artifact of a change, but a change that occurred many months ago.  We migrated our KMS service to a new server at a new site.  At some point in the past this machine must have been activated by manually entering slmgr /skms <ip of server>.  This disables auto discovery of the KMS service with no obvious indications.  To re-enable auto discovery enter slmgr /ckms.  Then you can enter slmgr /ato and verify it activates.

Hope this helps someone.

KMS configuration for non-domain joined hosts

September 16, 2011 10 comments

We are getting ready to deploy HBSS on our network per security guidlines.  Going through the settings we found out that the McAfee ePO server isn’t supposed to be domain joined.  Kinda goofy but that’s easy to deal with.  As we read further it says that if the ePO server is virtualized then the host can not be domain joined.  Fine, so we  repurpose an old server, install the OS but it’s not activating because it’s not domain joined.  Here is the simple solution.

First, change the product key if needed using these: http://technet.microsoft.com/en-us/library/ff793406.aspx

Next open a command prompt and enter slmgr.vbs /skms [ip address] where [ip address] is the address of your KMS server.

Then type in slmgr.vbs /ato and it should activate.
