In Microsoft Windows NT, a type of domain in an enterprise networking environment that includes file, print, and other resources for users throughout the enterprise. Resource domains are part of a master domain model or multiple master domain model enterprise-level implementation of Windows NT. Resource domains simplify resource administration by separating the administration of resources from the administration of user accounts.
In a master domain model implementation of Windows NT, an account domain - or master domain - contains user accounts for every user in the enterprise and is usually located at corporate headquarters. Servers and workstations at branch offices belong to other domains called resource domains.
A trust relationship is established so that each resource domain in the enterprise trusts the account domain. Users at branch offices who want to log on to the network simply log on to the account domain even though their workstations are located within resource domains. Administrators at branch offices are responsible for managing only the resources (file and print shares, Web servers, database servers, and so forth) for their own domain and are not involved in account management.
