We are currently setting up a Windows 2012 R2 server that has a DNS role installed. We are getting to retire a 2008 standard server that has Terminal Services and DNS installed on it. The 2008 box only had an external zone setup. Also, the 2008 box was never a domain controller so the zone was not an Active Directory Integrated zone. We created a single zone on the new 2012 box called ourcompany.com. This was accomplished by a zone transfer from the 2008 box as a secondary zone and then changed to Primary. The zone transferred without issue. Our domain register is pointed to the 2008 box and the 2012 box. They require 2 nameservers. We have stopped the DNS service on the 2008 box but can't resolve names on the 2012 box as DNS is running. Also, the 2012 box has a CNAME record pointing to the 2008 box to goto remote.ourcompany.com but all we receive is this page cannot be displayed. It is answering on port 443 and we feel the certificate is valid. Any help would be appreciated.

Thanks in advance !

Hi John,

On Server 2012, ensure DNS Server service is running and it is listening on the specific IP addresses. Right click on DNS server in DNS management console. Click Properties and choose Interfaces tab.

To verify if the server is offering DNS service.  We could use nslookup on client.

Configure Server 2012 as Preferred DNS server on client. Open Command Prompt and type nslookup. Then make a query and check the results.

For further analysis, we could perform a network capture.

Here is the guide for Network Monitor:
