  • The domain controller authenticates a user using the data stored in the Active Directory.

  • Thankfully, this guide gives you the safe method to change the IP address of the domain controller and change the system name.
Software to hide your IP address

Domain Controllers (DCs) are actively used for authenticating users and the devices connected to the domain.

Because of these works, they are best set up and left as is. This becomes important in terms of their hostname and network details.

Changing the IP of the domain controller may not be ever required but a time may come when you change it.

Moreover, domain controllers are assigned to a static IP address so they are reliable and discovered across the network without any issues.

While changing the IP address of the domain controller may cause certain issues for the administrator, because of its critical nature.

However, if the DC is not hosting any other roles, changing IP isn’t a big problem and can be done easily.

In this guide, we will show you exactly how you can change the IP of the domain controller safely and with no issues. Let us get right into it.

How do I find the IP address of my domain controller?

  1. Open the Start menu.
  2. Type Command Prompt and open it as an administrator.
  3. Execute the below command and press Enter. set userchange IP of domain controller cmd
    • If the USERDNSDOMAIN isn’t displayed then likely the server isn’t a domain member. You may want to consult with your Network Admin because it will be required in the later steps.
    • You need the USERDOMAIN value for the DCDiag test.
  4. Type the below and press Enter. nslookup
  5. Execute the below command and press Enter. set type=all
  6. Type the below command and press Enter. _ldap._tcp.dc._msdcs.<DOMAIN_NAME>change IP of domain controller press enter
    • Replace the <DOMAIN_NAME> with the USERDNSDOMAIN value you got in Step 3.
  7. This DNS query will display the SRV record of each domain controller.
  8. Check for hosts containing the same name or the same IP address. Notably, each entry should have a unique hostname and IP address.
  9. To exit out of nslookup, enter: exit

Using the above steps, you would be able to find the IP address of your domain controller. The steps may look a bit too much but it is for those who know what they are doing.

How do I change the system name and IP address from the domain control network?

1. Rename the system name

1.1. Using System Properties

  1. Download the Remote Server Administration Tools.
  2. Launch the installer.
  3. Read and accept the license and click I accept.
  4. After the installation is complete, open the RSAT tool.
  5. On the start screen, click on Server Manager.

  7. Right-click the FRS Member object and click Rename.
  8. Type the new name of the domain controller.

3. Update the DFS Replication member object

Is a domain controller the same as Active Directory?

We won’t give you complex terminologies as we want you to understand terms easily. An Active Directory is like a database. It stores information of users and computers as objects.

On the other hand, the domain controller is a service that runs Active Directory and uses the data stored by the AD for authentication and giving access to the user. Notably, a DC or domain controller manages the security policies of Windows NT or Windows Server.

So, the easiest way to remember the difference between Active Directory and DC is that Active Directory handles your identity and security access, on the flip side the Domain Controllers authenticate your authority.

That is it from us in this guide. We hope that we gave you the complete information on how you can change the IP of the domain controller. Let us know in the comments below if you come across any issues while following the above steps.
