They can be triggered when the refresh interval of the primary zone s SOA resource record expires. They can be triggered when a secondary server boots up. In these first two cases, the secondary server initiates an SOA query to find out whether any updates in the zone have occurred. Transfers occur only if the zone database has been revised.

When a zone transfer initiates, the secondary server performs either an incremental zone transfer (IXFR) query or an all zone transfer (AXFR) query to the master server. Computers running Windows 2000 Server and Windows Server 2003 perform IXFR queries by default. Through IXFR queries, only the newly modified data is transferred across the network. Computers running Windows NT Server do not support IXFR que ries and can perform only AXFR queries. Through AXFR queries, the entire zone database is transferred to the secondary server. Primary DNS servers running Windows Server 2003 support both IXFR and AXFR zone transfers. Figure 5-26 illustrates the transfer query process between secondary and master servers.

Note You do not need to configure zone transfers or notification among domain controllers or DNS servers in Active Directory integrated zones. For the servers within these zones, transfers are conducted automatically.
Practice: Deploying a Secondary DNS Server
In this practice, you create a secondary zone and then configure zone transfers between the two zones.
Exercise 1: Configuring a Secondary Zone
In this exercise, you install a DNS server on Computer2 and then configure the new DNS server to host a secondary zone.
Important The following exercise assumes that you have installed the DNS server on Computer1 by using the Windows Components Wizard (as described in 4, Lesson 3). In this case, zone transfers from the Domain1.local zone are enabled by default but restricted to authoritative name servers. If instead you have installed the DNS server on Computer1 by using the Manage Your Server window to add the DNS server role, zone transfers for all locally hosted zones are disabled by default. In this case, before beginning this exercise, be sure to enable zone transfers for the Domain1.local zone and restrict zone transfers to serv ers listed on the Name Servers tab.
1. From Computer2, log on to Domain1 as Administrator. Remember to specify the password you originally assigned to the Administrator account on Computer1.

2. On Computer2, install the Windows Support Tools, as explained in Lesson 2 of 3, Monitoring and Troubleshooting TCP/IP Connections. Windows Support Tools includes the Dnscmd command-line utility. 3. On Computer2, install the Domain Name System (DNS) Windows subcomponent of the Networking Services Windows component, as explained in Lesson 3 of 4, Configuring DNS Servers and Clients. For the purposes of this exer cise, you can safely dismiss any messages or errors you receive about Computer2 having a dynamically assigned IP address. Do not change the address configura tion on Computer2. 4. Once the installation of the Domain Name System (DNS) subcomponent is com plete, open a command prompt. 5. At the command prompt, enter the following command: dnscmd computer1 /recordadd domain1.local @ ns computer2.domain1.local. This command adds an NS record in domain1.local for Computer2, which makes Computer2 an authoritative server in the zone. By default, when a DNS server has been installed by using the Windows Components Wizard, zone transfers are allowed only to authoritative servers. 6. On Computer2, open the DNS console. 7. In the DNS console tree, right-click Forward Lookup Zones and select New Zone. 8. In the New Zone Wizard, click Next. 9. On the Zone Type page, select the Secondary Zone option, and then click Next. 10. On the Zone Name page, in the Zone Name text box, type domain1.local and then click Next. 11. In the Master DNS Server page, in the IP Address text box, type 192.168.0.1, click Add, and then click Next. 12. On the Completing The New Zone Wizard page, click Finish. 13. In the DNS console tree, expand Forward Lookup Zones and select the Domain1.local node. 14. Right-click the Domain1.local node, and then select Transfer From Master. 15. If the zone fails to load, wait 1 minute and then try again. Repeat this step until the zone loads successfully. 16. When a copy of the domain1.local zone appears in the DNS console on Computer2, take a few moments to browse the zone properties dialog box and the items on the zone s Action (shortcut) menu. 17. Right-click the DNS node in the DNS console, and then click Connect To DNS Server. The Connect To DNS Server dialog box opens.
