Hi,
I have promoted the new AD server DC02 ( Windows server 2012 R2) but getting error opening DNS that " Server could not be contacted. Error: DNS service is unavailable".
Even when I am trying to replicate from DC01 to DC02 from Site-Services NTDS setting I am getting error of
"
The following error occured during the attempt to synchronize naming context domain.com from dc01 to dc02: The replication operation was preempted.
This operation will not continue."
And I am getting below events continuously id DC02

Log Name: DNS Server
Source: Microsoft-Windows-DNS-Server-Service
Date: 7/28/2016 4:21:19 AM
Event ID: 4013
Task Category: None
Level: Warning
Keywords: Classic
User: N/A
Computer: DC02.domain.com
Description:
The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS data
might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet
Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed.
