I would like to know what FSMO roles are and what would happen if one role has failed. Automatically, who are assigned as FSMO? Would there be a difference in transferring and seizing an FSMO role? Please explain what role should we avoid seizing and why.
Difference in transferring and seizing an FSMO
FSMO or Flexible Singe Master Operations are specialized domain controllers with different set of tasks where data transfer and updating methods are used. There are at least 5 FSMO roles in a forest. They are Schema Master, Domain Naming Master, Infrastructure Master, Relative ID(RID) Master and PDC Emulator.
If an FSMO role failed, it can be seized and transferred to another domain controller then back again once the system is back online.
It would not be best to seized Domain naming master, Schema master and RID master as after they were seized you could not bring online the domain controller performing the role previously.
