Problem with Name resolution in DNS server 2012 R2

Hi All,

We are having DNS role on Server 2012 R2. some of our clients has changed their Public IPs.

when we are resolving those name from  our Local DNS server, it first try to resolve previous IP, if try again then resolve to new IP. we check dns Cache, there is no cache and there is no old records.

  • Not sure what is meant. In an active directory domain public DNS should not be used. DC and all clients / members should have the static address of DC listed for DNS and no others such as router or public DNS

      It is local DNS and using Forwarder for name resolution
