"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Apologies if you are aware of this but note that RMS is not related to administering Active Directory as such.

You dont need these CALs to edit AD but you would need one for each user that consumed RDS services in your environment.
