I have faced this issue for my HUB CAS server on hyper-v as virtual machine

The root cause of that is whenever for windows patching \ server maintenance I stopped its NLB service and after patching rebooted server, again starting the NLB service, in this frame some how record get deleted automatically

Then I have to run ipconfig /registerdns to populate that record

Not sure why its happening...the issue happens only with my both CAS servers
The fix I have done is to enabled advanced view in DNS console and then uncheck "scavenge this resource record when become stale" check mark in that host(A) record properties
