A Windows Server foundation work provides you with many benefits, including the following. ?? Core protocols for work connectivity between puters and other Transmission Control Protocol/Inter Protocol (TCP/IP) patible devices. TCP/IP is a suite of standard protocols for connecting puters and building works. TCP/IP is work protocol software provided with Microsoft174。 Windows174。 operating systems that implements and supports the TCP/IP protocol suite. ?? Automatic IP addressing with Dynamic Host Configuration Protocol (DHCP). Manual configuration of IP addresses on all puters on your work is timeconsuming and less flexible than dynamically providing puters and other devices with IP address leases from a DHCP server. ?? Name resolution services, such as Domain Name System (DNS) and Windows Inter Name Service (WINS). DNS and WINS allow users, puters, applications, and services to find the IP addresses of puters and devices on the work using the work basic input/output system (NetBIOS) name or Fully Qualified Domain Name of the puter or device. ?? A forest, which is one or more Active Directory domains that share the same class and attribute definitions (schema), site and replication information (configuration), and forestwide search capabilities (global catalog). ?? A forest root domain, which is the first domain created in a new forest. The Enterprise Admins and Schema Admins groups, which are forestwide administrative groups, are located in the forest root domain. In addition, a forest root domain, as with other domains, is a collection of puter, user, and group objects that are defined by the administrator in Active Directory Domain Services (AD DS). These objects share a mon directory database and security policies. They can also share security relationships with other domains if you add domains as your anization grows. The directory service also stores directory data and allows authorized puters, applications, and users to access the data. ?? A user and puter account database. The directory service provides a centralized user accounts database that allows you to create user and puter accounts for people and puters that are authorized to connect to your work and access work resources, such as applications, databases, shared files and folders, and printers. A foundation work also allows you to scale your work as your anization grows and IT requirements change. For example, with a foundation work you can add domains, IP subs, remote access services, wireless services, and other features and server roles provided by Windows Server174。 2020 and Windows Vista174。. 6 About this guide This guide is designed for work and system administrators who are installing a new work or who want to create a domainbased work to replace a work that consists of workgroups. The deployment scenario provided in this guide is particularly useful if you foresee the need to add more services and features to your work in the future. It is remended that you review design and deployment guides for each of the technologies used in this deployment scenario to assist you in determining whether this guide provides the services and configuration that you need. Network hardware requirements To successfully deploy a foundation work, you must deploy work hardware, including the following: ?? Ether, Fast Ether, or Gigabyte Ether cabling ?? A hub, Layer 2 or 3 switch, router, or other device that performs the function of relaying work traffic between puters and devices. ?? Computers that meet the minimum hardware requirements for their respective client and server operating systems. Note This guide depicts the use of four server puters. In some cases, such as on small works, you can use fewer servers. For example, you can install DHCP and WINS on the same server rather than on separate servers. What this guide does not provide This guide does not provide instructions for deploying the following: ?? Network hardware, such as cabling, routers, switches, and hubs ?? Additional work resources, such as printers and file servers ?? Inter connectivity ?? Remote access ?? Wireless access ?? Client puter deployment Note Client puters running Windows Vista and Windows XP are configured by default to receive IP address leases from the DHCP server. Therefore, no additional DHCP or Inter Protocol version 4 (IPv4) configuration of client puters is required. 7 Technology Overviews The following sections provide brief overviews of the required and optional technologies used to create a foundation work. Active Directory Domain Services A directory is a hierarchical structure that stores information about objects on the work. A directory service, such as AD DS, provides the methods for storing directory data and making this data available to work users and administrators. For example, AD DS stores information about user accounts, such as names, passwords, phone numbers, and so on, and enables other authorized users on the same work to access this information. DNS DNS is a name resolution protocol for TCP/IP works, such as the Inter or an anization work. A DNS server hosts the information that enables client puters to resolve easily recognized, alphanumeric DNS names to the IP addresses that puters use to municate with each other. DHCP DHCP is an IP standard for simplifying management
