These roles can be on same DC as well but no two DCs should have same roles. Schema Master : Schema master controls the Schema changes in any active directory forest. Active directory Schema is the combination of attributes of AD objects. Any changes to this schema are controlled by Schema Master. We can have only one DC in entire forest that can have schema master roles assigned. Domain Naming Master : Domain Naming master controls addition or deletion of domains in a forest. As we know the active directory replication will not work if there is no proper time synchronization between Domain Controllers.
Active Directory AD is pretty much the go-to domain authentication services for enterprises all over the world and has been since its inception in Windows Server Back then, AD was pretty unsecured and had some flaws that made it particularly difficult to use. For example, if you had multiple domain controllers DCs , they would compete over permissions to make changes. Over the last few decades, Microsoft has introduced numerous enhancements, patches, and updates that have drastically improved AD functionality, reliability, and security.
The other DCs fulfilled automation requests. However, people quickly realized that if the master DC goes down, no changes could be made at all until it was back up again.
So, Microsoft had to rethink. The solution they came up with was to separate the responsibilities of the DC into numerous roles. That way, if one of the DCs goes down, another can take over the missing role. Please check your email including spam folder for a link to the whitepaper! Those 5 FSMO roles are as follows:.
Now, why is it important to know about GC here? Because GC and infrastructure master should not be placed in the same domain controller. If you happen to do that, the infrastructure master will stop working as the GC gets precedence.
But, if you have a large forest with multiple domain controllers, the presence of both GC and infrastructure master will cause problems. We have multiple domains that look up to a GC server. Inside one domain, we make a change to the group membership and the infrastructure master knows about this change.
As you can see. FSMO roles prevent conflicts in an active directory and, at the same time, give you the flexibility to handle different operations within the active directory.
They can be broadly divided into five roles, out of which, the first two are for the entire forest while the remaining three pertain to a particular domain.
