The ability of the container hierarchy in next generation Windows NT Directory Services to nest Organizational Units within Domains (as well as within other OUs) provides a hierarchical name space which administrators can use to reflect their organization and to delegate administrative control. A container contains a list of contents, which could be major company divisions. In this scenario, it's then possible to select a division below a previous division and open it, and so on. Moving to a container hierarchy such as this with a finer-grained administrative model solves many problems. Large domains will still be possible. Finding things will still be easy, because everything that exists in the domain tree will show up in the global catalog, a service that allows users to easily find an object, regardless of where it is in the tree.
