  • Change DNS IP records

    Hi, I recently changed IP's on my DC's at site B to Internal (Private) IP's and mapped external (Public) IP's to the Internal IP's on my firewall, but now the other DC's at site A only knows them by their Internal IP's and can't contact them to replicate with them.

    How can I change the DNS records to my DC's at site A to see my DC's at site B?

    Do I just change the existing records (SRV, Hosts, etc...) to the External IP's?

    If Site A and Site B in different forests, that means you need to use "Forwarders" in the DNS for both sites.

    Site A ---> Forward DNS to Site B
    Site B ---> Forward DNS to Site A

      We only have one domain so...

      So far, I changed the IP in DNS to the External IP's. I think it's working, I'll keep you updated.

        Replication is taking place over the Internet?.... without a VPN? Set up a VPN. Then all your internal address will be resolved throughout the domain.

          Is this related to the other question you have open???

          Should really keep the questions together as we can then follow them through.
