  Hello,

  i had migrated from 2008 R2 Domain controller to 2016, all FSMO roles transferred to 2016 server. after migration existing clients machines not resolving new server DNS, it gives below error. 

   C:\Users\administrator.CLOUD>nslookup
  DNS request timed out.
      timeout was 2 seconds.
  Default Server:  UnKnown
  Address:  192.168.201.11

  new servers are able to resolve 2016 server DNS without any issue.

  i did not demoted 2008 R2 domain due to DNS issue. i tried registering DNS manually but no luck 

  Hi,

  Please note that the Active Directory & DNS (non-development) forums have been migrated to the new Microsoft Q&A platform, I suggest asking over here:

  Active Directory
  https://docs.microsoft.com/en-us/answers/topics/windows-active-directory.html

  DNS
  https://docs.microsoft.com/en-us/answers/topics/windows-dhcp-dns.html

  Best regards,
