2. FSMOROLES
Stands for Flexible Single Master Operation
There are 5 types of FSMO roles :
• Schema master
Forest Wide role
• Domain Naming master
• RID master
• PDC emulator Domain Wide Role
• Infrastructure master
3. SCHEMAMASTERFSMOROLE
• The schema master FSMO role holder is the DC responsible for performing
updates to the directory schema .
• This DC is the only one that can process updates to the directory schema.
• Once the Schema update is complete, it is replicated from the schema master
to all other DCs in the directory.
• There is only one schema master per forest.
4. DOMAINNAMINGMASTERFSMOROLE
• The domain naming master FSMO role holder is the DC responsible for making
changes to the forest-wide domain name space of the directory.
• This DC is the only one that can add or remove a domain from the directory.
• It can also add or remove cross references to domains in external directories.
5. PDCEMULATORFSMOROLE
• The PDC emulator is necessary to synchronize time in an enterprise.
• Responsible for Password changes performed by other DCs in the domain .
• Account lockout is processed on the PDC emulator.
6. INFRASTRUCTUREFSMOROLE
• When an object in one domain is referenced by another object in another
domain, it represents the reference by the GUID
• The infrastructure FSMO role holder is the DC responsible for updating an
object's SID and distinguished name in a cross-domain object reference.
• The Infrastructure Master (IM) role should be held by a domain controller that is
not a Global Catalog server(GC).
• If the Infrastructure Master runs on a Global Catalog server it will stop updating
object information because it does not contain any references to objects that it
does not hold.
7. TRANSFERINGFSMOROLES
• Schema master Active Directory Schema
• Domain Naming master Active Directory Domain and trust
• RID master
• PDC emulator Active Directory Users and computer
• Infrastructure master
