| Although there are various ways to install and configure DNS, the most straightforward and complete process involves invoking the Configure Your Server Wizard and subsequent Configure a DNS Server Wizard. The process detailed in this section illustrates the installation of a standard zone. Multiple variations of the installation are possible, but this particular scenario is illustrated to show the basics of DNS installation. If DNS Is Installed... If DNS is already installed on a server but not configured, start the procedure from step 7. Running the Configure Your Server Wizard When you're running the Configure Your Server Wizard, as noted in step 3, and you select the typical configuration, the networking components for DNS and Active Directory Domain Controller will be installed automatically at this point. If you select the custom configuration in the Configure Your Server Wizard, you need to follow steps 4 through 21. Installation of DNS on Windows Server 2003 is straightforward, and no reboot is necessary. To install and configure the DNS service on a Windows Server 2003 computer, follow these steps: -
Choose Start, All Programs, Administrative Tools, Configure Your Server Wizard. -
Click Next on the Welcome screen. -
Make sure that the listed prerequisites have been satisfied and click Next to continue. The Configure Your Server Wizard will then perform a network test. -
Select the DNS Server Component and click Next. (If you are installing Active Directory with DNS, you need to select Domain Controller as well, although this procedure is not outlined here.) -
Verify that the options to Install DNS Server and Run the Configure a DNS Server Wizard to Configure DNS are selected and click Next. -
After DNS is installed, you might be prompted for your Windows Server 2003 CD. If so, insert it and click OK when prompted. -
The Configure a DNS Server Wizard is then started automatically, as illustrated in Figure 13.4. (Or, if DNS is already installed, install it manually by choosing Start, Run and typing dnswiz.exe .) Figure 13.4. The Configure a DNS Server Wizard. -
On the Welcome screen for the Configure a DNS Server Wizard, click Next to continue. -
Select Create Forward and Reverse Lookup Zones (Recommended for Large Networks) and click Next. -
Select Yes, Create a Forward Lookup Zone Now (Recommended) and click Next. -
Select the type of zone to be createdin this case, choose Primary Zoneand click Next. If the server is a domain controller, the Store the Zone in Active Directory check box is available. -
Type the name of the zone in the Zone Name box and click Next. -
At this point, you can create a new zone text file or import one from an existing zone file. In this case, choose Create a New File with This File Name and accept the default. Click Next to continue. -
The subsequent screen allows a zone to either accept or decline dynamic updates. In this case, enable dynamic updates by selecting the Allow Both Nonsecure and Secure Dynamic Updates radio button and clicking Next. -
The next screen allows for the creation of a reverse lookup zone. Here, select Yes, Create a Reverse Lookup Zone and click Next. BEST PRACTICE: When Enabling Dynamic Updates to Be Accepted by Your DNS Server When enabling dynamic updates to be accepted by your DNS server, be sure you know the sources of dynamic updated information. If the sources are not reliable, you can potentially receive corrupt or invalid information from a dynamic update. | -
Select Primary Zone and click Next. -
Type in the network ID of the reverse lookup zone and click Next. (The network ID is typically the first set of octets from an IP address in the zone. If a class C IP range of 10.1.1.0/24 is in use on a network, you would enter the values 10.1.1, as illustrated in Figure 13.5.) Figure 13.5. Reverse lookup zone creation. -
Again, you are offered the option to create a new zone file or to use an existing file. In this case, choose Create a New File with This File Name and click Next to continue. -
Again, you are presented the option for dynamic updates. In this case, select Allow Both Nonsecure and Secure Dynamic Updates and click Next to continue. -
The next screen deals with the setup of forwarders, which will be described in more detail in the "DNS Zones" section later in this chapter. In this example, choose No, It Should Not Forward Queries and click Next to continue. -
The final window, shown in Figure 13.6, displays a summary of the changes that will be made and the zones that will be added to the DNS database. Click Finish twice to finalize the changes and create the zones. Figure 13.6. The final steps of the Configure a DNS Server Wizard. You Might See a Pop-up Dialog Box Depending on your network connectivity, you might see a pop-up dialog box between the two clicks to finish your DNS changes in step 21. If you are not connected to a LAN, you will see an error dialog box regarding searching for root hints. Although the dialog box notes the root hint error, if you click OK, DNS will still be configured successfully, so this is just an information note. |
