I have a server in UK server as a domain controller in a new forest (abc.com) and plan to have another server place in another city. This new server is also role as a domain controller of 123.com.
When i run the dcpromo to add this new tree to an existing forest, everything goes smooth. The problem starts when i need to authorize the dhcp server and it says that you need an enterprise admin to authorize is (Access is Denied)
I log in to the abc.com domain. I try to add the admin user from 123.com domain to Enterprise Admin group, I cant even search for the abc.com domain administrator account. The search window only let me find contact and other object from 123.com
I do a lot of research about it and end up i have to rebuild the server again.
Pls help as i really need this domain topology to be implemented. Thanks
