【正文】 you want to use is not already registered to another anization. If the domain name that you want to use is available, contact your Inter service provider (ISP) to confirm that the domain name is available and to help you register your domain name. Your ISP might set up a DNS server on its own work to host the DNS zone for your domain name or it might help you set up a DNS server on your work for this purpose. Creating internal DNS domain names For your internal domains, create names that are related to your registered Inter DNS domain name. For example, if you register the Inter DNS domain name for your anization, use a DNS domain name such as for the internal, fully qualified DNS domain name and use CORP as the NetBIOS name. If you want to deploy DNS in a private work, but you do not plan to create an external namespace, you should still register the DNS domain name that you create for your internal domain. If you do not register the name, and you later attempt to use it on the Inter or you use it to connect to a work that is connected to the Inter, the name might be unavailable. Creating DNS puter names When you create DNS names for the puters on your work, develop and follow a logical DNS puternaming convention. This makes it possible for users to remember easily the names of puters on public and private works, which facilitates access to work resources. Use the following guidelines when you create DNS names: ?? Select puter names that are easy for users to remember. ?? Identify the owner of a puter in the puter name. For example, andrewdixon indicates that Andrew Dixon uses the puter, and pubsserver indicates that the puter is a server that belongs to the Publications department. ?? As an alternative, select names that describe the purpose of the puter. 10 For example, a file server named pastaccounts1 indicates that the file server stores information related to past accounts. ?? Do not use capitalization to convey the owner or purpose of a puter. DNS is not case sensitive. ?? Match the AD DS domain name to the primary DNS suffix of the puter name. The primary DNS suffix is the part of the DNS name that appears after the host name. ?? Use unique names for all puters in your anization. Do not assign the same puter name to different puters in different DNS domains. For example, do not use such names as and . Also, do not use the same puter name when a puter is configured to run different operating systems. For example, if a puter can run Windows Server 2020 or Windows Vista, do not use the same puter name for both operating systems. ?? Use ASCII characters to ensure interoperability with puters running versions of Windows earlier than Windows 2020. For puter and domain names, use only the characters A through Z, 0 through 9, and the hyphen (). Do not use the hyphen as the first character in a name. In particular, the following characters are not allowed in DNS names: ?? ma (,) ?? tilde (~) ?? colon (:) ?? exclamation point (!) ?? at sign () ?? number sign () ?? dollar sign ($) ?? percent sign (%) ?? caret (^) ?? ampersand (amp。) ?? period (.), except as a separator between names ?? parentheses (()) ?? braces ({}) ?? underscore (_) ?? The number of characters in a name must be between 2 and 24. ?? Avoid nonstandard TLDs such as .local. Using a nonstandard TLD will prevent you from being able to register your domain name on the Inter. 11 Installing and Configuring AD DS and DNS When you create a new Active Directory Domain Services (AD DS) domain, the Active Directory Domain Services Installation Wizard installs the Domain Name System (DNS) server role by default. This ensures that DNS and AD DS are configured properly for integration with each other. Important Before you install AD DS and DNS on the first domain controller server in a new domain, ensure that the IP address of the server is static。 IP addresses, DNS server addresses, and other settings. The TCP/IP configuration steps in this section are required only if a DHCP server is not available. Configure the following settings for each DNS client: ?? TCP/IP settings for DNS ?? Host name and domain membership 20 The following procedures require you to log on with an account that belongs to the Administrators group on the client puter. To configure client settings on a puter running Windows XP 1. On the puter that you want to configure to use DNS, click Start, point to Control Panel, and then click Network Connections. 2. Rightclick the work connection that you want to configure, and then click Properties. 3. On the General tab, click Inter Protocol (TCP/IP), and then click Properties. 4. Click Use the following IP address. 5. In IP address, type the address of the client puter. 6. In Sub mask, type the sub mask of the domain controller. 7. In Default gateway, type the address of the default gateway of the domain controller. 8. Click Use the following DNS server addresses. 9. In Preferred DNS server, type the IP address of the DNS server that you installed in Installing and Configuring AD DS and DNS. Important 21 Do not use the IP address of a DNS server that is provided by your Inter service provider (ISP) as a primary or alternate DNS server. 10. Click OK, and then click Close. Note It is not necessary to restart the puter at this time if you intend to change the puter39。s name or domain membership in the following steps. 13. In Control Panel, click System and Maintenance, and then click System. 14. Under Computer name, domain, and workgroup settings, click Change settings. 26 15. On the Computer Name tab, click Change. 16. In Computer name, type the name of the puter (the host name). 27 17. Click Domain, and then type the name of the domain that you cre
