Currently we have a single forest / single domain model, ABC.com, i need to create a new domain in the forest but it needs to have an entirely separate name, 123.com
I am planning on creating a new domain in a new tree however i have some questions.
Does the server i promote to the 1st DC in this child domain need to be a member server in the existing domain first, or can i go straight from a workgroup to a DC in the new child domain
Currently we use AD integrated zones on our existing domain ABC.com,
Before promoting the server the the 1st child DC do we need to configure it to use the DNS servers in our current domain.
If the above is Yes, Once we install DNS on the server and its fully functional as a DC / DNS server in the new domain do we then change it back use itself as a DNS server
Do we need to create a conditional forwarder for each of the domains, so on domain abc.com a forwarder to 123.com and visa versa.
