I have just added a second domain controller at a client's site. It did not install DNS because the root domain controller accepts automatic updates for DNS. If the root DC were to crash, can I recover a copy of the DNS database for the existing DC through AD.
If So, how?
They have an existing DNS server for the same domain name but it is not AD intergrated and on a stand alone box. This was setup before me and the forest domain is the same as their web server domains (i.e. .com). I am trying to avoid setting up more uneeded DNS servers.
