Who is domain naming master

Since these actions are rarely performed in the forest, the Domain Naming Master is rarely put to use. Therefore, if the DC that holds this role is offline, the impact is minimal unless you are attempting to perform one of the actions listed above. The most common action from the list above is probably adding or removing domains.

This DC ensures consistency in domain in this respect. This role can be transferred at any time to any other DC in the forest. This role can be combined well with the Schema Master role. This is because both roles are used infrequently and do not add additional resource requirements on the server holding these roles. If this role needs to be transferred, you can use the Active Directory Domains and Trusts snap-in or by using the ntdsutil command line utility.

Internal crossRefs are created automatically by the system. External cross-references are created manually by Administrator, if necessary, explicitly declare the location of objects that are the AD forest. Approval of the domain rename — to rename a domain, the utility rendom. It is the job of the DNM to ensure that each domain created has a unique name within the forest. As well as ensuring that all domains in the forest have unique names, the DNM is also responsible for maintaining the authoritative list of domains in the forest.

This list is stored in the Partitions container, within the Configuration partition. 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.

It is the master of your domain names. And the PDC Emulator tells everyone else what time it is! If you have multiple domains in your forest, the Infrastructure Master is the Babelfish that lives between them.

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. Want to see how to do it?
