We set up an Active Directory Domain Controller in our office. The domain name that we used - main.mydomain.lcl is not known outside of the office. Obviously, this fully qualified domain name is not known to the outside world DNS servers, and is not pingable from the outside. We use a local cable company for Internet, and we get a dynamic address for our firewall.
Running the DNS test in DCdiag, it's failing. We're seeing no LDAP connectivity. It says that the server has invalid DNS servers which are the Google DNS servers that we point to in the outside world. No host records were found for this
DC. We're also seeing an error that all of our forwarders are invalid.
Is this happening because our main.mydomain.lcl is not known by the Google DNS servers? The DNS server has an SOA entry, an NS entry and an A entry for this server listed under it's FQDN - server10.main.mydomain.lcl. Do we need to add something else?
Thanks.
