In Computer name, type the name of the puter (the host name). 14. Click Domain, and then type the name of the domain that you want the puter to join. 15. If a second Computer Name Changes dialog box appears, in User Name, type the domain name and user name of an account that has permission to join puters to the domain. 16. In Password, type the password of the account. Separate the domain name and user name with a backslash, for example, domain\user_name. 22 17. Click OK to close all dialog boxes. To configure client settings on a puter running Windows Vista 1. On the puter that you want to configure to use DNS, click Start, and then click Control Panel. 2. In Control Panel, click Network and Inter. 3. Click Network and Sharing Center. In the Tasks pane, click Manage work connections. 23 4. Rightclick the work connection that you want to configure, and then click Properties. 5. On the Networking tab, click Inter Protocol Version 4 (TCP/IPv4), and then click Properties. 24 6. Click Use the following IP address. 7. In IP address, type the address of the client puter. 8. In Sub mask, type the sub mask of the domain controller. 9. In Default gateway, type the address of the default gateway of the domain controller. 10. Click Use the following DNS server addresses, and in Preferred DNS server, type the IP address of the domain controller that you installed in Installing and Configuring AD DS and DNS. Important Do not use the IP address of a DNS server that is provided by your ISP as a primary or alternate DNS server. 11. Click OK to exit. 12. If Inter Protocol Version 6 (TCP/IPv6) is selected, click it, and then click Properties. Perform the same steps as for TCP/IPv4, and then click OK and Close. Note 25 It is not necessary to restart the puter at this time if you intend to change the puter39。 that is, that it is not assigned by Dynamic Host Configuration Protocol (DHCP). DNS servers and Active Directory domain controllers must have static addresses to ensure that clients can locate the servers reliably. To install DNS with AD DS in a new domain 1. Click Start, point to Administrative tools, and then click Server Manager. 2. In the tree pane, click Roles. 3. In the results pane, click Add Roles. 4. On the Before You Begin page, click Next. 12 5. On the Select Server Roles page, click Active Directory Domain Services, and then click Next. 13 6. On the Active Directory Domain Services page, read the information and then click Next. 7. On the Confirm Installation Selections page, read the information and then click Install. 8. After AD DS installation has pleted, on the Installation Results page, click Close this wizard and launch the Active Directory Domain Services Installation Wizard (). 14 9. On the Wele to the Active Directory Domain Services Installation Wizard page, click Next. 10. On the Choose a Deployment Configuration page, click Create a new domain in a new forest, and then click Next. 15 11. On the Name the Forest Root Domain page, type the full DNS name (such as ) for the new domain, and then click Next. 16 12. On the Set Forest Functional Level page, select Windows Server 2020, and then click Next. 13. On the Additional Domain Controller Options page, make sure that DNS server is selected, and then click Next. 17 Note A message box informs you that a delegation for this DNS server cannot be created. This is normal and expected for the first domain controller in a new forest. Click Yes to proceed. 18 14. On the Location for Database, Log Files, and SYSVOL page, type the location in which you want to install the database, log, and system volume (SYSVOL) folders, or click Browse to choose a location, and then click Next. Note You can safely accept the default locations unless you know that you have a reason to change them. 15. On the Directory Services Restore Mode Administrator Password page, type a password to use to log on to the server in Directory Services Restore Mode, confirm the password, and then click Next. 19 16. Review the Summary page, and then click Next to begin the installation. 17. After the AD DS installation pletes, click OK to restart the puter. Configuring Client Settings By default, Domain Name System (DNS) clients are configured to allow Dynamic Host Configuration Protocol (DHCP) to automatically assign the clients39。) ?? apostrophe (39。 operating systems, such as Windows 2020, Windows XP, Windows Server 2020, and Windows Vista. DNS is a requirement for deploying the Active Directory Domain Services (AD DS) server role. Integrating DNS with AD DS makes it possible for DNS servers to take advantage of the security, performance, and faulttolerance capabilities of AD DS. Typically, you anize your DNS namespace (that is, the association of domains, subdomains, and hosts) in a way that supports your plan for using AD DS to anize the puters on your work. Understanding the DNS namespace The following illustration shows how the DNS namespace is anized. 7 A DNS name consists of two or more parts separated by periods, or dots (.). The last (rightmost) part of the name is called the toplevel domain (TLD). Other parts of the name are subdomains of the TLD or another subdomain. The names of the TLDs are either functional or geographical. Subdomains usually refer to the anization that owns the domain name. Functional TLDs suggest the purpose of the anization that has registered a subdomain in the TLD. The following table shows some of the most mon functional TLD names.
