I‘ve active directory 2008R2 domain on Sydney, Perth, Melbourne, in Sydney site root domain was installed reset of the Perth and Melbourne are installed with child domain.
We have office in London and Basingstoke London office configured with root domain Basingstoke office configured with child domain.
Each forest is configured with active directory integrated DNS; there are two active directory forests available in my hand. Now we are in need of enabling the forest trust. Once forest is enabled both side users can access files and folders and other network resources.
Over all users count for both forests is 2410.
Now my question is how to implement the stub zone in this scenario how does it could be technically helpful for me in this situation.
