Abstract: On a Microsoft Exchange 2013/2016 Server you might see the event ID 205 or 16025 (No DNS servers could be retrieved from network adapter 00000000-0000-0000-0000-000000000000) in the event log and wish to solve them.

The solution according to Microsoft Technet is the following:

Microsoft Exchange 2013/2016 required that the "Register this connection’s addresses in DNS" is checked in the NIC card option (If you use a NIC for the interside replication and another for the access, then only the NIC for the access and not the for the replication should have set that option!).

You can do that as well via Get-NetworkConnectionInfo

Note: If you enable the option this might cause the following errors in the eventlog:

The system failed to register host (A or AAAA) resource records (RRs) for network adapter

So make sure that the exchange server could register his IP on the non replication NIC in the DNS! Additional make sure that the NIC order is set correctly and that the REPLICATION NIC is not the first one!
