I'm unable to change DNS IP automatically in thousands of domain-joined client computers. How to forcibly change DNS IPs to domain-joined client computers with member servers. Please guide me on how to change DNS IP Automatically in thousands of Domain Joined Client Computers and member servers by running scripts applied to group policy.
Actually, one of my compliance requirements is that they have existing three domain controllers and around 2,500 domain-joined client computers, and 100+ domain-joined member servers with 250 branches under them with 3 DNS IPs set consistently in all clients' computer network DNS properties.
Now let's come to my main point, my all 3 domain controllers have running on windows server 2012 OS, so my 3 domain controllers will be migrated to windows server 2022 OS, and in total, my 5 domain controllers will be new, and these new 5 domains controllers will be on a different subnet IP with Windows Server 2022.
So, I have to change and assign DNS IPs centrally by running the PowerShell script through group policy or any automation scripting process. There is no option to entry or set DNS IP manually on my client's computer network adapter. I have to do it through automatic DNS registration.
Please guide me hands-on, on how can I complete this task more efficiently and smoothly. My main topic is how to change DNS IP Automatically in Thousands of Domain Joined Client Computers.

If the IP addresses are static, you'd probably be better off using a script and a file with the host/IP address combinations of each machine. A file of 2500 lines wouldn't be very large.
Keep in mind that any change in IP address while your script is running on the remote machine will disconnect the script and report a failure even though the change happens.
DNS registration of the new addresses may present a problem (duplicate A and PTR records) if the machines are configured to update their own A/PTR records. Having DHCP manage the IP assignment and the updating of DNS is the cleaner solution.

Good day!! Hope you are doing well.
Yes, all of my client computers have the static IP address.
It is possible to give me any documentation link or source for using the script?
Thanks for your cooperation. Have a nice time ahead.

2023-06-24T21:20:23.4933333+00:00 Well, before you go charging off to write a script (or to find one), some things to consider:
- Are all of the target machines identically configured?
- For each machine, do you know either the interface alias, or the interface index of the NIC you'll be modifying? Remember, you'll always have at least two interface IDs (and indexes) for one of the NICs: the interface for 127.0.0.1 and the interface for the LAN.
- You'll have to exclude any interfaces for WiFi and Bluetooth adapters in each machine.
- NICs that cannot obtain an address will have APIPA address in the 169.254.0.0/16 network (Bluetooth adapters will probably fall into that category). Exclude those fro your list.
Get a good inventory of your network before you decide that you want to do this instead of using DHCP.

2023-06-24T23:34:55.85+00:00 Ans: Yes, configured and domain-joined only just need to change DNS IPs.
Ans: No, need at least two interface IDs, One is enough because all client computers don't need the internet only need to have data communications.
