PDC Emulator will be responsible for time synchronization
try this command netdom query fsmo (it will show FSMO roles in current Domain) netdom query fsmo /d:Domain FQDN (It will show FSMO roles in other domain mentioned after /d:
true
First Domain controller in the forest
Domain naming master - rid
There is no releation between FSMO roles and replication. However Infrastructure master role replicate the cross domain group membership changes.
PDC emulator has the role to synchronize time in the domain
FSMO stands for the Flexible single Master Operation, there are 5 types of FSMO Schema Master Domain Naming Master Infrastructure Master Remote ID Master(RID) PDC Emulator Regards Anil Mahapatra
There are five roles:They are further classified in two1. Forest RolesSchema Master - As name suggests, the changes that are made while creation of any object in AD or changes in attributes will be made by single domain controller and then it will be replicated to another domain controllers that are present in your environment. There is no corruption of AD schema if all the domain controllers try to make changes. This is one of the very important roles in FSMO roles infrastructure.Domain Naming Master - This role is not used very often, only when you add/remove any domain controllers. This role ensures that there is a unique name of domain controllers in environment.2. Domain RolesInfrastructure Master - This role checks domain for changes to any objects. If any changes are found then it will replicate to another domain controller.RID Master - This role is responsible for making sure each security principle has a different identifier.PDC emulator - This role is responsible for Account policies such as client password changes and time synchronization in the domain
the server which holds the FSMO role it cna be changed by few methods 1. go to admin option->users and computers -> select domain->rt click fsmo roles gives three tabs of domain fsmo role holder-> change from there. 2 for other roles go to admin option->use site -> forest level roles you can cchange in the properties of each fsmo role holder. 3. NTDS util will help you to see the roles and transfer
infrastructure master
Schema Master and Domain naming master.
