Hi All,
We have two domains and single forest for our clients. Both the Forest and Domain functional levels are 2008 R2. Both the parent and chield domains are with AD integrated DNS zones. More then one Network adapters are configured on some of our DCs. Backup and Management IPs are configured on the same. During our regular DC health check reports we found that replication test to these DCs are failed (Those who has multiple NIC). We come to know that all the domain controllers are registered their static A records on their DNS zones. I understand that this is part of the Netlogon process of DC, however the issed DCs has registered 2 or 3 IPs for the same hostname on the DNS zones. When I deleted the other unwanted A records, it creates automatically after some time. I am not sure what is the cause and how can we avoid of Multiple host A record creation for the same Domain Controllers.
