How to change primary DNS to domain controller

If you want to change your primary DNS server to a domain controller, the process is fairly straightforward. You can use the Windows Server 2008 R2 DNS Manager tool, nslookup, or the DNS Server Manager tool in Windows Server 2003.

First, open the DNS Manager tool. If you are using Windows Server 2008 R2, you will need to open the Server Manager tool and click on the DNS tab.

If you are using Windows Server 2003, you will need to open the DNS Server Manager tool and click on the Add Roles and Features Wizard button.

On the DNS Servers tab, click on the Add button.

In the Add DNS Server dialog box, type the primary DNS server name (for example, dc02.contoso.

com) and click on the Server button.

On the Select Server Type dialog box, select the Active Directory Domain Services check box and click on the Next button.

On the Select Primary Zone dialog box, select the appropriate zone (for example, contoso.com) and click on the Next button.

On the Select DNS Server Settings dialog box, select the Use the same primary DNS server for all zones check box and click on the Next button.

On the Confirmation dialog box, click on the Finish button.

Now open the nslookup utility. Type the primary DNS server name (for example, dc02.

contoso.com) in the nslookup command line and press the Enter key.

If you are using Windows Server 2008 R2, you will see the following output:

If you are using Windows Server 2003, you will see the following output:

In the nslookup output, you will see the address of the domain controller that is serving as the primary DNS server. In this example, the domain controller is dc02.com.
