Azure ATP Health - Low success rate of active name resolution using reverse DNS
Hello! Got an alert about Domain controller health where issue is low success rate of active name resolutiong using reverse DNS: Sensor X, has a low success rate of active name resolution using r...
I checked also ATP sensor error logs and no new errors even if the ATP keeps alerting.
I am in a process of upgrading that 2012 R2 DC to 2019 so lets see if it alerts after that.
I have one 2019 DC and two 2012 R2 DCs in my environment. Only that one 2012 R2 is alerting about that name resolution and that is the fsmo role owner and DHCP server (where it differs from the 2019 DC which does not alert)
