How to Change the Domain Controller Name

The domain controller (DC) on a network is the main server that hosts permissions and security authentication on a Windows 2003 network. The DC was introduced in Windows NT and persists as a main server in any medium- to large-sized network. When a user logs into the domain, the credentials are checked with the DC. The DC then sets the permissions for the user on the network. When installing a Windows server operating system, you are prompted for a name to give to the server. However, you can change that name in the system properties.

Instructions

1. Log in to the domain controller using an administrator account. Changing the DC name requires administrative rights.

2. Right-click the "My Computer" icon on the desktop. From the menu items, select "Properties." This opens a configuration window.

3. Click the "Computer Name" tab. Click the "Change" button. Click the "OK" button at the warning screen.

4. Enter a new name in the dialog box. Press the "OK" button. A dialog window appears asking you to enter the password for the domain administrator account. Enter the credentials and click the "OK" button.

5. Reboot the domain controller for the changes to take effect.

Tips & Warnings

• Only Windows Server 2003 DCs have the ability to be renamed.
