History
I've been using Server 2008R2 as a KMS server for years. Last year, we installed the patch to allow it to function for Windows 8.1/2012R2 clients. It worked flawlessly.
I recently decommissioned that server (I manually uninstalled the KMS host key, unpublished the DNS entry, shutdown the server, and deleted its VM). Furthermore, I deleted the _VLMCS srv record from DNS, and confirmed that no trace of the server remained
- anywhere.
Then, I built a new 2012R2 server, added the Volume Licensing Role, installed the KMS host key, and activated it. I verified the DNS entry was properly created, and confirmed clients are registering with the new server. Everything worked
great -- that was three weeks ago.
Problem
Today, I have a problem with a new Windows installation not activating. I discovered that the DNS SRV record for the KMS server was gone.
I went to the server and confirmed that DNS publishing is enabled, and I restarted the sppsvc service. The DNS record was not created, so I rebooted the server. The DNS record still not created. I checked the event logs, and there are no
entries indicating a failure, nor are there entries indicating an attempt to register the DNS record.
It seems that the KMS server simply isn't publishing the DNS record.
Workaround
I manually created the SRV record, but I shouldn't need to do this and I don't like it. Hence, I am posting this looking for a proper "fix".
Speculation/Conclusion
Does Windows Server 2012R2 have a bug where it doesn't publish the DNS entry, except for the very first time? Does anyone have any helpful ideas? Does anyone else have this problem?
Other
This problem is very similar to:KMS publish DNS record
Thanks in advance for your efforts to help me!
