SUMMARY
The step-by-step article describes how to set up a Windows 2000 DNS server as the primary Domain Naming System (DNS) server in an existing DNS domain. When an existing DNS domain structure is in place, it may be necessary to replace the current primary DNS server with a new Windows 2000 DNS server. DNS is the software that puts names to number mappings on computers.

The following list describes items that are used as examples in this article:
 * The domain name is &quot;microsoft.edu&quot;.
 * The IP address range is 192.168.0.0-192.168.0.255.
 * The new Windows 2000 server IP address is 192.168.0.7, and the old primary DNS server IP address is 192.168.0.2.
 * &quot;W2K-DNS&quot; is the Windows 2000 server name.

To Install DNS

 * 1) The administrator of the computer has to log on to the Windows 2000 server to install DNS.

To Transfer Records from the Current DNS Server

 * 1) Click Start, point to Programs, point to Administrative Tools, and then click DNS to start the DNS Administrative console. Double-click W2K-DNS (the server name) to expand it.
 * 2) Right-click Forward Lookup Zones, click New Zone to start the wizard, and then click Next.
 * 3) Click Standard Secondary for the zone type, click Next, type the zone name (in this example, &quot;microsoft.edu&quot;), and then click Next.
 * 4) Type the IP address of the current primary DNS server (in this example, 192.168.0.2), click Add, click Next, and then click Finish.
 * 5) Right-click Reverse Lookup Zones, click New Zone to start the wizard, click Next, click Standard Secondary for the zone type, and then click Next.
 * 6) In the Network ID box, type 192.168.0, and then click Next.
 * 7) Type the IP address of the current primary DNS server (in this example, 192.168.0.2), click Add, click Next, and then click Finish.

How to Change the Role of a DNS Server
After you transfer all of the records have been transferred, you must remove the old DNS server from the network, and set the DNS server as the primary DNS server. To set the DNS server as the primary DNS server:
 * 1) Click Start, point to Programs, point to Administrative Tools, and then click DNS to start the DNS Administrative console. Double-click W2K-DNS (the server name) to expand it.
 * 2) Double-click Forward Lookup Zones, right-click the Microsoft.edu zone, and then click Properties.
 * 3) Click the General tab, click Change under Type, and then click either Standard Primary or Active Directory Integrated as the new type, depending on whether or not this computer is a domain controller (DC). Click OK.
 * 4) Change the setting under Allow Dynamic Updates to Yes if this server is for a Windows 2000 Domain.

NOTE: The server is now set as a primary DNS server for the DNS domain space.

You Are Unable to Transfer the Zone File

 * 1) Verify the existing DNS server allows zone transfers.
 * 2) Verify that the new DNS server IP address is allowed for zone transfers.
 * 3) If the zone file is locked, the transfer should occur after a maximum of 10 minutes.

It Is Necessary to Change the IP Address to Match the Old DNS Server
It may be necessary to change the IP address of the new server to match the IP address that the old DNS server used. This should be done to prevent having to make changes on all clients or secondary servers to point to a new IP address for the primary DNS server. When you use the same IP address for a live domain on the Internet, you can prevent downtime that may occur while waiting on Internic authorities to propagate the change of the IP address. To change the IP addresses:
 * 1) Right-click My Network Places, and then click Properties.
 * 2) Right-click Local Area Connection, and then click Properties.
 * 3) Click Internet Protocol (TCP/IP), and then click Properties.
 * 4) Change the IP addresses to match the old DNS server (in this example, 192.168.0.2).
 * 5) Change the DNS settings to match the IP address of this server.
 * 6) Click OK.
