I added two new Windows Server 2012 R2 Domain Controllers to the existing Windows Server 2008 R2 DCs. I am in the processes testing that everything is in order before decommissioning the W2K8 DCs.
On the Linux host, I removed the IPs pointing to Windows Server 2008 DNS and added the DNS IPs of Windows Server 2012 R2 in /etc/resolv.conf . After the update, I am not able to query the records from the entire zone. Here is the error I am getting:
command : host -v -a -l abc.com
Host abc.com not found : 5 (REFUSED)
: Transfer failed
I am able to query the records as soon as I update the /etc/resolv.conf with the old DNS server IPs.
