It also emphasizes the Domain Name System (DNS), which is an Internet and TCP/IP standard name service and required for Windows 2000 domains and directory services based on Active Directory technology. Active Directory directory services integrate the Internet concept of a namespace with Windows 2000 directory services. Active Directory directory services use DNS as the domain naming and location service, so Windows 2000 domain names are also DNS names. In fact, the core unit of logical structure in Active Directory directory services is the domain. In this kit, you will learn how to install, navigate, and administer the Windows 2000 Active Directory directory services.

Those of you who run networks on Windows 2000 know the benefits of using Active Directory for managing user information and permissions. You also know what a bear it can be.

The Concise Guide to DNS and BIND provides the technical depth and expert-level information needed to understand and administer DNS and BIND. Domain Name System (DNS) is a distributed Internet directory service. It is used mainly to translate between domain names and IP addresses, and to control Internet email delivery. Most Internet services rely on DNS to work, and if DNS fails, Web sites cannot be located and email delivery stalls. BIND (Berkeley Internet Name Daemon) is an implementation of the Domain Name System (DNS) protocols. Some of the topics covered are setting up a DNS server and client, compiling and configuring BIND, and setting up root servers on private networks. The Concise Guide to DNS and BIND also features expert knowledge on firewall rules, Dynamic DNS (DDNS), debugging and logging, plus new features in BIND 8.2.2. The book also offers introductory information on BIND 9.

Операционные системы (ОС) семейства Windows Server 2003 являются эволюционным развитием серверной платформы Windows 2000 Server, также включившим в себя многие средства систем Windows XP. Нелишне напомнить, что ОС Windows 2000 имеют внутренний номер версии 5.0, а системы Windows XP вышли под номером 5.1. Семейство Windows Server 2003 (сборка (build) 2790) имеет версию 5.2. (Грубо говоря, можно считать, что версия 5.2 равна версии 5.1 плюс Service Pack 1 плюс серверные службы плюс обновления, вышедшие с момента появления Windows XP.) Семейство Windows Server 2003 включает в себя четыре редакции (версии) операционных систем (их назначения и характеристики рассматриваются ниже): Windows Server 2003, Standard Edition; Windows Server 2003, Enterprise Edition; Windows Server 2003, Datacenter Edition; Windows Server 2003, Web Edition. Несколько упрощая ситуацию, эти редакции можно рассматривать как различные конфигурации (комплектации) одного и того же "базового" ядра. Большинство системных сервисов поддерживается во всех редакциях, в то время как отдельные сервисы присутствуют или, наоборот, отсутствуют в более "мощных" моделях. В двух следующих разделах как раз и рассматриваются различия редакций Windows Server 2003 в плане функциональных возможностей и требований к аппаратным средствам. В этой книге мы будем рассматривать возможности и службы, единые для всех четырех версий, поскольку именно они представляют интерес для широкого читателя. Поэтому в книге используется общее имя "Windows Server 2003", за которым может стоять любая редакция ОС семейства Windows Server 2003. Системы Windows Server 2003 сохранили многие черты своих предшественниц — Windows 2000 Server и Windows XP, поэтому пользователям, знакомым с этими системами, будет легче освоить новую систему, чем пользователям систем линейки Windows 9x/ME.
