Out of curiosity, I am am thinking about splitting our customers internal FSMO roles that are currently on one server and putting 3 (Infrastructure, RID, and PDC) on a second server. That way we have 1 server that hosts the Schema and Domain name roles and one server hosting Infrastructure, RID, and PDC roles. I've already made sure that the servers are GC's and from a performance perspective things look good. Would you guys recommend to keep all the FSMO roles on the same server or split up the roles? Just a side now, I am restructuring the Active Directory for our customer with new OU's, fixing up GPO's, etc... so I figured I would add the FSMO role management to the task.
