網域名稱系統」(DNS)Domain Name System (DNS)

適用於:Windows Server(以每年次管道)、Windows Server 2016Applies To: Windows Server (Semi-Annual Channel), Windows Server 2016

網域名稱系統」(DNS) 是通訊協定構成 TCP/IP,業界標準系列,並在一起 DNS Client 和 DNS 伺服器提供電腦名稱 TO-IP 位址對應名稱解析度服務到電腦和使用者。Domain Name System (DNS) is one of the industry-standard suite of protocols that comprise TCP/IP, and together the DNS Client and DNS Server provide computer name-to-IP address mapping name resolution services to computers and users.

注意

本主題中,除了下列的 DNS content 使用。In addition to this topic, the following DNS content is available.

在 Windows Server 2016 DNS 是您可以使用伺服器管理員或 Windows PowerShell 命令安裝伺服器角色。In Windows Server 2016, DNS is a server role that you can install by using Server Manager or Windows PowerShell commands. 如果您安裝新的 Active Directory 森林和網域,DNS 會自動安裝 Active Directory 與全球目錄伺服器的樹系和網域。If you are installing a new Active Directory forest and domain, DNS is automatically installed with Active Directory as the Global Catalogue server for the forest and domain.

Active Directory Domain Services (AD DS) 會使用 DNS 網域控制站的位置機制。Active Directory Domain Services (AD DS) uses DNS as its domain controller location mechanism. 主要 Active Directory 作業執行時,驗證,例如更新,或搜尋時,電腦使用 DNS 尋找 Active Directory 網域控制站。When any of the principal Active Directory operations is performed, such as authentication, updating, or searching, computers use DNS to locate Active Directory domain controllers. 此外,網域控制站會使用 DNS 不到彼此。In addition, domain controllers use DNS to locate each other.

DNS Client 服務包含所有 client 和 server 版本的 Windows 作業系統,在與作業系統安裝時,預設執行。The DNS Client service is included in all client and server versions of the Windows operating system, and is running by default upon operating system installation. 當您的 DNS 伺服器的 IP 位址設定 TCP/IP 上網時,DNS Client 查詢 DNS 伺服器探索網域控制站,並將電腦的名稱解析為 IP 位址。When you configure a TCP/IP network connection with the IP address of a DNS server, the DNS Client queries the DNS server to discover domain controllers, and to resolve computer names to IP addresses. 例如網路使用者的 Active Directory 帳號 Active Directory domain 登入,DNS Client 服務查詢 Active Directory domain 的網域控制站找出 DNS 伺服器。For example, when a network user with an Active Directory user account logs in to an Active Directory domain, the DNS Client service queries the DNS server to locate a domain controller for the Active Directory domain. 當回應查詢 DNS 伺服器,並提供 client 網域控制站的 IP 位址時,client 連絡人的網域控制站和驗證程序就可以開始。When the DNS server responds to the query and provides the domain controller's IP address to the client, the client contacts the domain controller and the authentication process can begin.

Windows Server 2016 DNS 伺服器,並 DNS Client 服務使用 TCP/IP 通訊協定套件中包含 DNS 通訊協定。The Windows Server 2016 DNS Server and DNS Client services use the DNS protocol that is included in the TCP/IP protocol suite. DNS 是部分應用程式層的 TCP/IP 參考型號,如下所示。DNS is part of the application layer of the TCP/IP reference model, as shown in the following illustration.
