Flexible Single Master Operations Roles (FSMO)

Understanding FSMO roles is key to ensuring a stable network infrastructure for your Active Directory. Doug clears up the mystery.
Active Directory is "multiple-master". That means that all but the RODCs host a read/write copy of Active Directory. Some services do require that there is a single "master" copy. These are known as Flexible Single Master Operations roles, also known as FSMO.
In this excerpt from the Windows Server 2008R2 Administration Epic Live class, Senior Technical Instructor Doug Bassett explains the forest and domain FSMO roles and what can happen if the role goes offline.
This is an example of the real-world, online HD certification training done at StormWind.com.
