We are experiencing a situation with a client whereby a DNS Servers list of Interfaces keeps resetting to listen on all IP addresses.
There are two DNS servers in the domain, both of which are domain controllers. Both servers have two network cards with different IP address ranges on each. The purpose of this is one for production and one for DR,
To prevent DNS issues on the network, the DNS servers are set to only listen for DNS requests on the IPv4 address of the production network. However, every now and then (usually following a reboot or DNS service restart) a 410 DNS event is logged and the DNS configuration changes to listen to requests on all interfaces. This results in clients trying to resolve IP addresses on the DR network.
The box to register this adapter in DNS has been un checked on both NICs.
Any guidance greatly received.
