I am trying to setup a child domain to join an existing domain. Since DNS is required, I am confused. The first DC used itself as preferred DNS, and I can see all the records created when the active directory is installed.
For the second DC (probably located in a different location), is it setup to use the first DC as preferred DNS(knowing that wan link between to location exists)?
I have delegated the DNS for the child domain and created the A host pointing to the second DC on my first DC. When I promoted the second Server , it seems successful but the folders like _mscdcs for the second DC exists on the first DC and the loading is like 2 minutes as well.
So i'm thinking if I did this right. that if ever other server will exist like dhcp, will I just use the second DC as preferred DNS?
Child DC DNS = First DC
Will use SECOND DC as DNS
WIll follow DHCP
