Lesson 3: Installing the DNS Service

Now that you have been introduced to DNS, the Windows 2000 DNS Service, and name resolution, you are ready to learn how to install the Microsoft DNS Server Service on a computer running Windows 2000 Server.

Computers running Windows 2000 are configured as Dynamic Host Configuration Protocol (DHCP) clients by default. Therefore, you must configure TCP/IP with a static IP address before installing the DNS Server Service. Configure the following options on the server on which you are going to install the DNS Service:

• Assign a static IP address in the Internet Protocol (TCP/IP) Properties dialog box.
• Configure the appropriate IP address of the DNS server and DNS domain name. Using My Network Places, click the Advanced button in the Internet Protocol (TCP/IP) Properties dialog box to configure the advanced TCP/IP settings. On the DNS tab, type the DNS address and domain name.

Install the DNS Service anytime after the Windows 2000 initial setup, or you can choose to install the DNS Service during setup. In addition to installing the DNS Service and enabling the service automatically (without restarting the computer), the DNS installation process does the following:

• Installs the DNS snap-in and adds the DNS shortcut to the Administrative Tools menu. The DNS snap-in is the Microsoft Management Console (MMC) snap-in that you use to manage local and remote DNS name servers.
• Adds the following key for the DNS Service to the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS

• Creates the C:\Winnt\System32\Dns folder, which contains the DNS database files that are described in Table 3.3.

Table 3.3 DNS Database

Filename	Description
Domain.dns	The zone database file that maps host names to IP addresses for a zone.
z.y.w.x.in-addr.arpa	The reverse lookup file that maps IP addresses to host names.
Cache.dns	The cache file that contains the required host information for resolving names outside of authoritative domains. The default file contains records for all of the root servers on the Internet.
Root	The root file that controls how the DNS Service starts. In Windows 2000, the root file is optional, because the root settings are also stored in the registry.

In this practice you will configure TCP/IP as part of the preinstallation configuration required to install the DNS Service, and then you will install the DNS Service.

In this exercise, you will configure TCP/IP for DNS. This is part of the configuration you do to prepare to install Microsoft DNS Server.

1. Log on as Administrator.
2. Right-click My Network Places, and then click Properties.

The Network And Dial-Up Connections window appears.

3. Right-click Local Area Connection, and then click Properties.

The Local Area Connection Properties dialog box appears, displaying the network adapter in use and the network components used in this connection.

4. Click Internet Protocol (TCP/IP), and then verify that the check box to the left of the entry is selected.
5. Click Properties.

The Internet Protocol (TCP/IP) Properties dialog box appears.

6. Select Use The Following IP Address.
7. Type 192.168.1.201 in the IP Address box.
8. Press the Tab key to move the cursor to the Subnet Mask box, ensure that 255.255.255.0 is the value and leave the Default Gateway box empty.

If you are not using these suggested values, enter the IP address, Subnet Mask, and Default Gateway that you are using.

9. Ensure that the Use The Following DNS Server Addresses option is selected.
10. Type 192.168.1.201 in the Preferred DNS Server box.

11. Click Advanced.

The Advanced TCP/IP Settings dialog box appears.

12. Click the DNS tab.
13. In the DNS Suffix For This Connection box, type domain.com (if you are on a network, check with your network administrator to make sure it is OK to use this as your DNS domain name), and then click OK.
14. Click OK to close the Internet Protocol (TCP/IP) Properties dialog box.
15. Click OK to close the Local Area Connection Properties dialog box.
16. Close the Network And Dial-Up Connections window.

1. Right-click My Computer, and then click Properties.

The System Properties dialog box appears.

2. On the Network Identification tab, click Properties.

The Identification Changes dialog box appears.

3. Click More.

The DNS Suffix And NetBIOS Computer Name dialog box appears.

4. In the Primary DNS Suffix Of This Computer box, type domain.com, and then click OK.
5. Click OK to close the Identification Changes dialog box.

A Network Identification warning box appears, stating that you must reboot this computer for the changes to take effect.

6. Click OK.
7. Click OK to close the System Properties dialog box.

A System Settings Change box appears, asking if you want to restart your computer.

8. Click Yes to restart your computer.

In this exercise, you will install the Microsoft DNS Server Service.

1. Log on as Administrator.
2. Open Control Panel.
3. Double-click Add/Remove Programs.

The Add/Remove Programs window appears.

4. Click Add/Remove Windows Components.

The Windows Components wizard appears.

5. Click Networking Services, but do not select the check box to the left of the component.

7. Click Details.
8. In the Subcomponents Of Networking Services list box, select the check box to the left of Domain Name System (DNS).
9. Click OK.

You are returned to the Windows Components page.

10. Click Next.

The Configuring Components page appears, and a status indicator begins tracking the configuration process. After a few moments, the Insert Disk dialog box appears.

11. Insert the CD-ROM you used to install Windows 2000 on your computer, and then click OK.

Setup copies the required files to the hard disk.

12. Click Finish to close the Windows Components wizard.
13. Close the Add/Remove Programs window.
14. Close Control Panel.
15. Remove the CD-ROM.

There are some configuration changes you need to make before you install the Microsoft DNS Server Service. As a part of this preinstallation configuration, you should assign the computer on which you are going to install the DNS Service a static IP address, and you should configure the appropriate IP address of the DNS server and DNS domain name.

You can install the DNS Service anytime after the Windows 2000 initial setup, or you can choose to install the DNS Service during setup. In the practice portion of this lesson, you did the preinstallation configuration and then you installed the DNS Service. In addition to installing the DNS Service, the DNS installation process installs DNS and adds a shortcut for it to the Administrative Tools menu on the Start menu's Programs menu.
