A domain controller’s IP address may occasionally need to be changed, particularly if you want to modify the network address of its information system. To do so, you must first determine the IP address of the domain controller. This can be done by querying the DNS server for a list of all domain controllers in your network or by using a tool such as netsh ipconfig. If you are using DHCP, then you must also specify the new IP address when configuring your DHCP client.
If your domain controller does not host any additional, arbitrary roles, it shouldn’t be too difficult. We have mentioned steps below to change the IP address of your domain controller.
Steps to Change IP Address of Domain Controller
Open the PowerShell command prompt by right-clicking the PowerShell icon in the desktop taskbar and selecting Run as administrator.
Before proceeding, run the Diagnostic and Configuration Tool (DCDIAG) to ensure that the DC is functioning properly. If any problems are found, fix them before proceeding. ..
Open the Network and Sharing Center by right-clicking the network icon at the bottom right of the taskbar and selecting Open from the menu.
In the Change adapter settings window, click the network icon. In the Network window, right-click your adapter and select Properties. In the Properties window, on the General tab, under Adapter settings, click Change adapter settings. In the Change adapter settings window, under Network adapters, select your network adapter. In the Connections tab, under Local area connection properties, click Internet Protocol Version 4 (TCP/IPv4). In the Properties window for TCP/IPv4:, on the General tab, under IPv4 address properties, type in your IPv4 address and press Enter. On the Subnet mask property page, type in 255.255.255.0 and press Enter. ..
On the Properties screen, click the IP address tab and enter the new IP address.
In the TCP/IPv4 Properties dialog box, click the Properties button. In the General tab, set the following values: IP Address: 192.168.1.101 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.1.1 In the DNS tab, set the following values: Name Server 1: 192.168.1.254 Name Server 2: 208.67.222.222 ..
In the TCP/IPv4 dialog box, change the IP address (and subnet mask, if necessary). In this example, I’ll also change the entry for the primary DNS server to the new static IP address of the DC. Click OK to continue.
In the Network and Sharing Center, click on the Ethernet icon. In the Ethernet Properties dialog box, click on the Advanced tab. Under IPv4 Settings, select Use the following IP address. Enter 192.168.1.101 into the IP address field and press OK. Close the Network and Sharing Center. ..
Final Words
Changing the IP address of a domain controller is an important part of your IT infrastructure. When there is a change in the local subnet’s IP addressing scheme, it may be necessary to change the IP address allocated to a DC. This process can be concerning for administrators, but we have outlined steps that will help make the transition as smooth as possible. ..
