I have situation like that
AD root - test.com
child DC - hk.test.com ( this DC store example.com 's mailbox )
AD root - example.com
(When I create an account in example.com for user login, At the same time, I would also create the same mail-enable account in hk.test.com using exchange2003.
create user1 in example.com for login
create user1 in hk.test.com for email account)
And I have 2 choices
I would like to demote example.com and then dcpromo this server to become cn.test.com. Then, I cannot manage the account easily. But the duplicate account will be a problem when I join this computer to be cn.test.com. Is there any solution to solve the problem easily?
I have new server installed with windows2003, then, I join this server to be child DC called cn.test.com. But can I move the account from hk.test.com to cn.test.com, whose mailbox account is for example.com before.
What choice is better, or is there any other good solutions?
Thanks everyone to reply in advance
