How to enable Active Directory in Windows Server 2003

This step-by-step article describes how to install and configure a new Windows Server 2003-based Domain Name Service (DNS) computer in an existing DNS server environment with Active Directory enabled. This new Windows Server 2003-based DNS server provides local name resolution services for Windows clients and servers while working effectively with existing DNS server environments.
Adding a Windows Server 2003-Based DNS Server to an Existing Environment
To create a new Windows Server 2003-based DNS server, you must install Windows Server 2003 on a networked server. Because DNS is not installed by default when you install Windows Server 2003, you must install DNS on the server. You can install the Windows Server 2003-based DNS service during the installation of Windows Server 2003, or you can install it after the initial installation.
Installing Windows Server 2003-based DNS Services on an Existing Windows Server 2003 Computer

Click Start, point to Settings, and then click Control Panel.
Double-click Add or Remove Programs, and then click Add/Remove Windows Components.
In the Windows Components Wizard, click Network Services in the Components list, and then click Details.
In the Network Services dialog box, if the Domain Name System (DNS) check box is not already selected, click the check box to select it, and then click OK.
In the Windows Components Wizard, click Next to start the Windows Server 2003 setup. If prompted, insert the Windows Server 2003 CD-ROM into your computer's CD-ROM or DVD-ROM drive. The installer will copy

DNS and the tool files to your computer.
After the installation is complete, click Finish.

Windows Server 2003 DNS will be integrated into the existing DNS domain if
existing environment already has a DNS domain and an existing DNS structure, and enabled Active Directory, can the existing DNS domain The subdomain is delegated to the Windows Server 2003 domain. You must have a Windows Server 2003 DNS server installed to complete the following steps.
Creating a Delegate Subdomain for a Windows Server 2003-Based DNS Domain
With an existing DNS domain, you can delegate a subdomain of an existing DNS server to a Windows Server 2003-based DNS server. For example, if your domain name is mycompany.com, you can create a subdomain called windowsNET.mycompany.com. A Windows Server 2003-based DNS server has administrative rights to this subdomain.

To create a sub-domain, configure a primary DNS server DNS server to use the organization as a repeater. The forwarder provides recursive lookups for queries that are any queries that the DNS server receives but cannot answer based on its local area. When a forwarder is set up, the Windows Server 2003 DNS server is responsible for resolving all queries for the computers or resources contained within its own local domain. However, any queries outside this range will be forwarded directly to the organization's primary DNS server for resolution.

Note: This article describes the process from the perspective of a Windows Server 2003 DNS server. You must also set up a delegate record on the primary DNS server hosting the parent DNS namespace. This delegate record allows the primary DNS server to pass down the records of the Windows Server 2003-based DNS namespace to the Windows Server 2003-based DNS server. For help with performing namespace delegation, see the help file for your DNS server.
Add the organization's primary DNS server to the list of forwarders on the Windows Server 2003 computer
1. Click Start, point to Programs, click Administrative Tools, and then click DNS to open DNS Management Console."
2. Right-click the server's DNS Server object and click Properties.
3. Click the Forwarders tab, type the IP address of the DNS server to which you want to forward non-local queries, and then click Add.
4. Continue to add the IP address of any other DNS servers you want to use as a forwarder until you have added all forwarders.
5. Click OK to save your settings and return to the DNS Management Console.
  
  Troubleshooting
  The option to configure root hints or forwarders is not available
  If the DNS server is not detected during the initial configuration of Windows Server 2003 DNS, the system will usually The DNS server is designated as the root server and has the final permissions for all named resolution activities. Therefore, the new DNS server cannot forward any name resolution queries that it cannot resolve to another server or to the root server on the Internet. Therefore, a Windows Server 2003 DNS server that is configured as a root server disables the option to automatically add forwarders.
  
  If you later decide to integrate the DNS server into a larger DNS environment such as the Internet, you will need to delete the root forward lookup zone.
  
  To delete the root forward lookup zone:
  1. Click Start , point to Programs, point to Administrative Tools , and then click DNS to open the DNS Management Console.
  2. Expand your server's DNS Server object in the left pane of the console.
  3. Expand the forward search area .
  4. Click on the area marked with a period (.) and press the Delete key.
  5. Click OK to confirm that you want to delete this area.
