My company is setting up a child domain in another country and
connecting it to the parent domain via VPN. Can the DNS be installed
succesfully if the child domain is not already connected to the parent
domain. And if so how would this be done?
I'm not sure what you are trying to achieve. DNS is independent of
Active Directory but can reside on DCs. It can be "Active Directory
Integrated" which is a bad term because it implies that it is somehow
linked into the Active Directory. In fact the only Active Directory
service that it uses is replication. Think of DNS separately from Active
Directory and things may appear clearer.
Do you have a 'parent' domain in one site and separately set up child
Domain already set up in another site? If so, you cannot then connect
the child Domain into the parent Domain.
If you haven't created the child Domain yet, then I would first set up
DNS on a server in the child site, and ensure that DNS connectivity back
to the main DNS servers is working. Then I would set up the new child
Domain once you are sure that DNS is working properly.
You can set up the site's DNS so that it holds a copy of the parent's
zone and then use that DNS when setting up the child Domain.
Afterwards, when you have a working AD setup you could AD Integrate the DNS.
