What is the RID master FSMO role?
The Relative Identifier Master or RID master FSMO role is a domain level role. For each domain in the Active Directory forest, there is one RID Master. Each RID Master role is responsible to allocate active and standby Relative Identifiers (RIDs) pools to the domain controllers within their domain.
What is FSMO in Active Directory?
Active Directory extends the single-master model found in earlier versions of Windows to include multiple roles, and the ability to transfer roles to any DC in the enterprise. Because an Active Directory role isn't bound to a single DC, it's referred to as an FSMO role. Currently in Windows there are five FSMO roles:
Should FSMO roles be on the same DC?
Microsoft recommends carefully dividing FSMO roles and preparing a backup DC to take over each role. The PDC simulator and RID host should be on the same DC, if possible. The schema master and domain naming master should also be in the same DC. What is FSMO? The first section tells you the specific definition.
What are FSMO roles explain each role?
FSMO roles are services each hosted independently on a DC in an AD forest. Each role has a specific purpose, such as keeping time in sync across devices, managing security identifiers (SIDs), and so on. FSMO roles are scoped at either the forest or domain level and are unique to that scope, as shown below.

What is PDC and BDC?
A PDC is a Primary Domain Controller, and a BDC is a Backup Domain Controller. You must install a PDC before any other domain servers. The Primary Domain Controller maintains the master copy of the directory database and validates users.
Why do you need 2 domain controllers?
Actually, In a larger environment, at least two domain controllers at each physical site should be DNS servers. This provides redundancy in the event that one DC goes offline unexpectedly. Note that domain-joined machines must be configured to use multiple DNS servers in order to take advantage of this.

FSMO gives you confidence that your domain will be able to perform the primary function of authenticating users and permissions without interruption (with standard caveats, like the network staying up).
What is the role of a schema master?
Schema Master: The Schema Master role manages the read-write copy of your Active Directory schema. The AD Schema defines all the attributes – things like employee ID, phone number, email address, and login name – that you can apply to an object in your AD database.
What is the role of the Infrastructure Master?
Infrastructure Master: The Infrastructure Master role translates Globally Unique Identifiers (GUID), SIDs, and Distinguished Names (DN) between domains. If you have multiple domains in your forest, the Infrastructure Master is the Babelfish that lives between them. If the Infrastructure Master doesn’t do its job correctly you will see SIDs in place of resolved names in your Access Control Lists (ACL).
How many roles does a DC have?
Microsoft split the responsibilities of a DC into 5 separate roles that together make a full AD system.
What is a FSMO role owner?
The RID master FSMO role owner is a single DC responsible for handling RID pool requests for all DCs in a given domain. It is also responsible for deleting the object from the object's domain and placing it in another domain while the object is moving.
How many FSMO roles are there in Windows?
Since Active Directory roles are not bound to a single DC, they are called FSMO roles. Currently, in Windows, there are five FSMO roles.
What is FSMO in Microsoft?
What Is FSMO. What is FSMO? It is the abbreviation of Flexible Single Master Operations. It is a single host operation or operation host, which is a feature of the Microsoft Active Directory. FSMO is a set of dedicated domain controller (DC) tasks, used when standard data transfer and update methods are insufficient.

The schema master role manages the read-write copy of the Active Directory schema. The AD schema defines all the attributes that can be applied to objects in the AD database, such as employee ID, phone number, email address, and login name.
What is the purpose of time service?
The purpose of time service is to ensure the hierarchical relationship of Windows time service usage control authority and does not allow loops to ensure proper public time use. The PDC emulator of the domain is authoritative to the domain. The PDC simulator in the forest root directory is authoritative to the enterprise and should be configured to collect time from external sources.
What is the role of the Infrastructure Master?
The infrastructure master role converts globally unique identifiers (GUID), SID, and distinguished names (DN) between domains. If you have multiple domains in your forest, the infrastructure master is the Babelfish between them.

What is a DC schema?
This DC holds a read-write copy of your AD schema. Schema is essentially all the attributes associated with an object ( passwords, roles, designations, etc.). So, if you need to change a role on a user object, you’ll have to do it through the Schema Master.
Does schema master need to be online?
For schema master, for example, the DC only needs to be online during the update. The PDC, however, will need to be online and accessible at all time. For that reason, you need to make the necessary steps to ensure that the PDC emulator does not fall over.
Can you transfer FSMO roles to another domain controller?
If you know that a particular FSMO role is going to undergo scheduled maintenance, you should transfer the FSMO role to a different DC. If the worst should occur, and your FSMO role crashes, you can always seize the FSMO role to another domain controller as a last resort.

Responsible for updating the SID of a specific object and updating the full name of the object reference between different domains. There can be one for each domain in the forest.
Can you put Infrastructure Master on any domain controller?
If all DCs in the domain have the Global Catalog role (today this is the configuration recommended by Microsoft), you can place the Infrastructure Master role on any domain controller. If not, move the Infrastructure Master role to a domain controller that doesn’t have the Global Catalog role enabled;
Can FSMO roles be split?
According to Microsoft recommendation, the Best Practice is to split the FSMO roles between the different domain controllers.
