Double DNS server entry showing in DNS Manager in Windows Server 2016 Standerd

Question

I've installed Win 2016 Standerd Server and in the process of course I've add ADDS, DNS roles. In the beginning I didn't find anything wrong, but when I look at the DNS console now, I see two DNS servers that are seemingly identical - with exception of the name. One is listed only with server name (abdserver), the other is listed server name (abdserver.domain suffix) (registered domain name, example- rbsa.local):

Hi @chirag darji

Thanks for posting in Q&A platform.

I have tested in my lab and found that this phenomenon was due to the order we configured DNS role and AD DS role.

If we add DNS role first, then add AD DS role and promote this server to a domain controller, then there will be 2 DNS server in DNS Manager. One is named with hostname and another on is with FQDN of this server.

If we directly add AD DS role on this server and specify this domain controller capabilities as Domain Name System (DNS) server, then there will be only 1 DNS server in DNS Manager named with FQDN of this server.

Normally, we recommend directly add AD DS role and configure this server as DNS server in AD DS configuration wizard. Or if the DNS resolution can work correctly, I would suggest you could just ignore this issue.

Best Regards,
Sunny
