I have one Domain Controller in my school with the name of "ISCADKC"; I added a new replica domain as secondary.
Then I need to transfer the FSMO Roles from the First server to the second one to be as primary domain controller, and then I need to remove completely the First ONE.
I need to add [.com] to my Domain to be [ISCADKC.com], how can I change it without affecting problems for users?
I have around 70 computers joined to this domain?
Please any help.
Thank you in advance,
