disjoint namespace

Contributor(s): Toni Boger

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. The word disjoint is a synonym for separate. The computer with the suffix that doesn't match is called the disjoint.

In Active Directory, domain member computers may be able to function in a disjoint namespace with support in certain situations. However, network applications may not work because the applications assume the namespace is identical to the DNS suffix of all domain member computers.
