Microsoft Hyper-v server 2019 - issues with DNS on HYPERV Failover Cluster

Hello,

From few weeks , I have a problem with this error:

124031-hyperv-1.jpg

Can you help me how to resolve this error ?


I see that in DNS everything is ok , because I see no errors here. Everything is with OK status.

Did you have the same errors in your enviroment ? If yes, than how did you resolved it ? When I`ve had Microsoft hyper-v 2016 server, I didn`t have those errors.....They appeared only when I`ve had installed hyper-v 2019 server.

I have had this problem on multiple cluster types, not just Hyper-V. I've had Microsoft look at it, but all they did was poke around a bit and proclaim "there must be something wrong in your environment" without any suggestions or exploration into what that might be. So, there's no fix. But if you (manually or by script) fail the cluster core resources over before the machine account expiration/renewal period, then maybe you won't get the problem. Once every two weeks should suffice. If you do that and still have the problem, well, "there must be something wrong in your environment" is all we have.
