I am trying to add active directory to my new Windows 2008 Server Standard. I do not want to make the machine at this time a domain controller. I might do that at a later time but not at this point. What i want to do is add active directory to this server. I have always used the disk that came with my exchange server in the past but since i see the new roles screen open when my computer turns on i think i want to use that instead. My question is which active directory role do i select to get active directory and system manager on my server??? I believe it is Active Directory Rights Management Services but i just need a little confirmation to make sure i dont need the domain services as well.
