Hi,
Thank you for posting in Q&A!
So far I haven't researched any information of such event. Unfortunately, it seems that there's no official records about this kind of event log.
May I ask does your server encountered any problems regarding failed attempts at server authentication through DNSSEC and TSIG/SIG?
If you have encountered this kind of issue, please check the event viewer to see if exists more detailed information.
Hope you have a nice day : )
Gloria
