18.1 FSMO Roles and Limitations
FSMO roles also known as Operations Master are roles performed by the domain controller to
facilitate replication.

default the first domain controller in the domain holds all the roles. The five FSMO roles are as
follows:
RID Master
PDC Emulator Master
Infrastructure Master
Schema Master
Domain Master

particular domain
Limitations

By default the editing or creation of Group Policy Objects (GPO) is always done from the GPO copy
located in the PDC Emulator's SYSVOL share.
