Error event 12293 in application log for Security-SPP on KMS server

In my case KMS was activated on windows server 2008 R2, with dns publishing option enabled, and server started to log event 12293 in its application log:

Publishing the Key Management Service (KMS) to DNS in the '' domain failed.
This server didn't register its SRV dns record. In same domain there was already another KMS server, and reason for this event and behavior was that this new kms server didn't have the permission to update already existing _VLMCS srv record. Resolution for this kind behavior was to add permission for _vlmcs dns record for the newly activated KMS server. There is also microsoft KB for this event .
