Best Practices for Operation Master Roles on Domain Controllers


We have an environment of 4 domain controllers and we just wanted to know which are the best practices for the operations master roles (RID, PDC, Infrastructure...) Is it better to leave all 5 on one server or is it better to divide them?

Thank you in advance!

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

only 4 DC total....fine keeping all on one box
in environments that are much larger you could split them but many times all on one server is fine

Well, there are two types of FSMO roles: Schema and Domain.  It is generally considered best practice to at least group them if you don't keep them all together.

Schema: Schema Master and Domain Naming Master.
Domain: PDC Emulator, RID Master, Infrastructure Master.

There are a few other considerations to make, depending on the complexity of your enterprise.  With just four DCs, I would suggest keeping them all together.  But, that is personal preference.
