We have over 3000 servers, all of sudden today over 500 lost DNS records, we are quickly trying to re-registering them. Found that scavenging was set to 1 hour (immediately disabled), also found that ALL the Dynamic A records have timestamp of today
but different hours. Every single record. 7/8/2016 1AM (2AM or 3 AM, 4 AM)...but all stamped today...why? No errors or anything in event viewer. Any suggestion on where to check for root cause?
