How to Create DNS Records in Active Directory

Introduction: DNS (Domain Name System) is a critical component of any network infrastructure, including Active Directory. DNS records help map human-friendly domain names to their corresponding IP addresses, enabling effective communication and resource access. In an Active Directory environment, properly configuring DNS records is essential for the smooth functioning of services, such as domain authentication, name resolution, and service location. In this article, we will guide you through the process of creating DNS records in Active Directory.

Step 1: Accessing the DNS Management Console

  • Log in to a domain controller or a server with administrative privileges.

  • Open the"Server Manager" by clicking on the corresponding icon in the taskbar or by searching for it in the Start menu.

  • In the Server Manager, click on "Tools" in the upper-right corner and select "DNS" from the dropdown menu. This action will launch the DNS Management Console.

Step 2: Navigating to the DNS Zone

  • In the DNS Management Console, expand the server name in the left pane to view the server's DNS zones.

  • Locate the relevant forward lookup zone where you want to create the DNS record. This zone will correspond to your Active Directory domain (e.g.,

Step 3: Creating a DNS Record

  1. Right-click on the desired zone and select "New Host (A or AAAA)" or "New Alias (CNAME)" from the context menu, depending on the type of record you want to create.

  • "New Host (A or AAAA)" is used to create a record that maps a hostname to an IP address.

  • "New Alias (CNAME)" is used to create a record that provides an alias or nickname for an existing hostname.

2. In the "New Host" or "New Alias" dialog box, enter the relevant details:

  • For "New Host":

  • Name: Enter the hostname or subdomain name for the record (e.g., server1 or app).

  • IP address: Specify the corresponding IP address for the hostname.

  • Leave the "Create associated pointer (PTR) record" checkbox selected if you want a reverse lookup record to be created automatically.

  • For "New Alias":

  • Alias name: Enter the desired alias or nickname for an existing hostname.

  • Fully qualified domain name (FQDN) for target host: Specify the target hostname to which the alias will point.

3. Click "Add Host" or "Add Alias" to create the DNS record.

Step 4: Verifying the DNS Record

  • To ensure the successful creation of the DNS record, you can perform a simple test.

  • Open the command prompt on a client computer connected to the Active Directory domain.

  • Type "nslookup" followed by the hostname or alias you created in the previous steps.

  • If the DNS record was created correctly, the command prompt will display the corresponding IP address or the target host's FQDN.

Conclusion: Creating DNS records in Active Directory is an essential task for ensuring proper name resolution and resource access within the network. By following the steps outlined in this article, you can easily create DNS records in the DNS Management Console. Remember to maintain accurate and up-to-date DNS records to support the smooth operation of your Active Directory environment.
