Creating a new domain tree under the forest

Question

Hi
I have one primary domain and one additional domain at moment so I want to create a new domain tree under the forest however during the configuration it gives me the below message ?
the last time I installed without tick marking "Create DNS Delegation" option I had a lot of issue in replication and in DNS between my forest domain and this new tree domain.
my main question would be:
1- how to resolve this ?
2- how to create a manual DNS delegation in Parent zone.?
please suggest ?

Answer 1

Hi greeMann,
This is an expected behaviour and it can be ignored.  The error message occurs because this is the first DNS server so there is not a DNS server available to create the delegation from. 
If you are not concerned that people in other domains or on the Internet will not resolve DNS name queries for computer names in the local domain, you can disregard the message and click Yes.
