Above, we have talked about domains trusting accounts in other domains by using global groups. This implies the use of trust relationships which have been established between the domains. We also mentioned that in large corporations, multiple domains could exist. These links are used to provide user and resource management across the various domains. There may be one or more BDC s.
Network administrators have full administrative rights on all servers in the domain.
This model is suited to organizations which require centralized management of user accounts and ease of administration, and where the number of users is relatively low. Note that it possible for an organization to have multiple single domain models. This could occur where, for security or other reasons, functional groups need to be separate. Trust Relationships Windows NT server domain models are like building blocks, which can be combined in various ways to build larger and larger networks. The use of trust relationships allows single domain models to be interconnected, thus sharing user accounts and resources across domains.
