What is a disjoint namespace?

A disjoint namespace occurs when one or more domain member computers have a primary Domain Name Service (DNS) suffix that does not match the DNS name of the Active Directory domain of which the computers are members. In a contiguous namespace, the primary DNS suffix matches the Active Directory domain name.

What do you call one or more trees with disjointed namespaces?

Explanation: A forest is made of one or more trees (although most people think of a forest as two or more trees). A forest varies from a tree because it uses disjointed namespaces between the trees.

What is contiguous namespace?

A contiguous namespace links a child container to its parent by adding one and only one more identifier to the beginning of the DNS name. For example, if the parent Domain was named COMPANY and the child Domain was named AMERICA. COMPANY, then these two domains would form a contiguous namespace.

What defines one or more domains that are part of the same contiguous namespace?

You can group domains that are part of the same contiguous DNS namespace within the same domain tree. Conglomerates are made up of multiple individual companies in which each company typically wants to maintain its own identity and, therefore, its own namespace.

What are some examples of disjoint namespaces?

For example, assume that a domain controller for the Active Directory domain named na.corp.fabrikam.com that uses a primary DNS suffix of corp.fabrikam.com registers host (A) and IPv6 host (AAAA) resource records in the corp.fabrikam.com DNS zone.

How to deploy exchange in a disjoint namespace?

Exchange 2013 supports the following three scenarios for deploying Exchange in a domain that has a disjoint namespace: Primary DNS suffix and DNS domain name are different: The primary DNS suffix of the domain controller isn’t the same as the DNS domain name. Computers that are members of the domain can be either disjoint or not disjoint.

What do you mean by disjoint Domain Name System?

Disjoint namespace is a scenario in which a computer’s primary domain name system (DNS) suffix doesn’t match the DNS domain name where that computer resides.

Is the Active Directory suffix the same in disjoint namespace?

Although Windows operating systems may support a disjoint namespace, applications that are written to assume that the primary DNS suffix is the same as the Active Directory domain suffix may not function in such an environment.
