242 Networking: A Beginner’s Guide Customize This Server The third section of the Initial Configuration Tasks window contains two simple options and two very powerful options. The two simple options are Enable Remote Desktop and Configure Windows Firewall. The two powerful options are Add Roles and Add Features. The Windows firewall is turned on by default. I recommend also enabling Remote Desktop, which you can use to administer a Windows Server 2008 server over the network using Remote Desktop Connection. Figure 16-11. Configuring networking 243 Chapter 16: Installing and Setting Up Windows Server 2008 Windows Server 2008 makes setting up the server to perform different roles a snap. Clicking the Add Roles link starts the Add Roles Wizard, as shown in Figure 16-15. If you are configuring the server as a file server, just check the File Services checkbox. To configure it as a web server using IIS, click the Web Server (IIS) checkbox. You can choose any combination of roles that you need, and the wizard will walk you through any necessary additional setup with a minimum of hassle. In this example, we are installing Windows Server 2008 as a stand-alone domain controller. Using the Add Roles Wizard, choose the Active Directory Domain Services role, and then click Next to install them. (You cannot install other roles at the same time as Active Directory Domain Services.) Figure 16-12. Configuring a TCP/IP address 244 Networking: A Beginner’s Guide The Add Features option allows you to install particular Windows Server 2008 features. When you add roles, any required features are automatically installed. Accordingly, you will not often need to add specific features to a Windows Server 2008 installation. I do, however, recommend that you look through the list in the Add Features Wizard, as shown in Figure 16-16, so that you understand the types of features are available. After the installation is complete (it usually does not take more than a few minutes), you need to run a program called DCPromo in order to create the new domain and complete the setup of the server. Figure 16-13. Setting the server name and workgroup or domain 245 Chapter 16: Installing and Setting Up Windows Server 2008 Creating a New Domain To install your new domain, follow these steps: 1. Open the Start menu, click Run, enter DCPROMO, and press ENTER. This starts the Active Directory Domain Services Installation Wizard, as shown in Figure 16-17. Click Next to continue. 2. The next wizard page lets you join an existing forest or create a new forest. For this example, we will create a new forest. Choose that option button and click Next to continue. Figure 16-14. Entering a new server name 246 Networking: A Beginner’s Guide CAUTION Join an existing forest only if you are the network administrator responsible for the existing Active Directory forest, and you are adding a new domain controller to that forest. If you are just evaluating and learning about Windows Server 2008, you should instead create a new forest. 3. You are prompted to enter the fully qualified domain name (FQDN) of the new forest root domain (nabg.com in this example), as shown in Figure 16-18. 4. You are prompted to enter a domain NetBIOS name. Usually, this will be the main portion of the domain name you entered for the FQDN of the forest root domain (for this example, the NetBIOS name NABG will be entered by default). If the default NetBIOS name is acceptable to you, click Next to continue. Figure 16-15. Using the Add Roles Wizard .
