than one domain. There is a derivative product of active directory, known as ADAM, which does support more than one domain in a single host platform. domain controller (pre-Windows 2000) A Windows NT® 4.0-based server configured as a PDC or as a BDC. domain controller (Windows 2000 and Windows Server 2003) A Windows® 2000-based server with active directory installed and enabled. The act of installing and enabling active directory necessarily causes a platform to become a domain controller. Each domain controller holds a single domain. A single domain controller cannot host more than one domain. See also Peer Master Domain Controller. Domain Mode See Mixed Domain Mode, Native Domain Mode, and functional levels. Domain Name System The DNS is a hierarchal distributed database used for name/address translation. DNS is the name space used on the Internet to translate computer and service named into TCP/IP addresses. Active directory uses DNS as its location service, and so clients find domain controllers using DNS queries. Active directory can be used to hold the data (for example, zone and forwarding records) that constitutes the DNS database used by the DNS service running on the domain controller. When DNS records in a Domain Controller are held in its active directory database, DNS zone transfers are handled as active directory replication operations and DNS and active directory are said to be "tightly integrated." domain tree See domain. domain tree root The first domain created in a domain tree. It might not be the forest root. forest A group of one or more active directory domain trees that mutually trust each other. All domain trees in a forest share a common schema, configuration, and global catalog. Each tree has a root domain and zero or more descendent domains, forming a contiguous name space. When a forest contains multiple trees, the trees collectively do not form a single contiguous name space. All trees in a given forest trust each other though transitive bidirectional trust relationships. Unlike a domain tree, a forest does not need a distinct name. However, the root of the first tree created in the forest is always referred to as the root of the forest. A forest exists as a set of cross-referenced objects and trust relationships known to all member trees. See also domain and forest root. forest root The first domain created in an active directory deployment. After the first domain is created, additional domains can be created as child domains of that root and/or as new roots of additional trees in the same forest within an enterprise active directory deployment. See also forest, domain tree root, and domain. Glossary 329
