Active Directoy site / DNS suffix

Question

Hello

I have a question. We have an AD DS and our domain name is companynet.local. By default, all computers stored in our AD DS are configured with companynet.local dns suffix (ex : computer1.companynet.local or server1.companynet.local). Our DNS servers are deployed on the same servers than our AD and are fully integrated with AD.

We will open a new physical site (our new datacenter) named DTC00. I created a new primary zone on DNS server with DTC00.mpanynet.local.

How I can configure my environment to add dns suffix DTC00.mpanynet.local automatically on server added on our AD to have for exemple, by default when the new server will be added on AD, the following fqdn : server1.DTC00.mpanynet.local or server2.DTC00.mpanynet.local ?

Regards

Hello JeromeCAR,

Thank you for posting in Microsoft Community forum.

Based on the description, do you want more than one FQDN for single machine in the domain?

You can refer to the similar thread below.

https://learn.microsoft.com/en-us/answers/questions/205925/can-we-set-multiple-fqdn-to-a-single-vm
Or the group policy below may be helpful.

To automatically add the DNS suffix "DTC00.mpanynet.local" to computers added to your Active Directory domain, you can configure the DNS suffix search list through Group Policy. Here are the steps:

1. Open the Group Policy Management Console.
2. Create a new Group Policy Object or edit an existing one.
3. Navigate to Computer Configuration > Policies > Administrative Templates > Network > DNS Client.
4. Enable the "DNS Suffix Search List" policy.
5. Add "DTC00.mpanynet.local" to the list of DNS suffixes.

Once this policy is applied to your computers, they will automatically append "DTC00.mpanynet.local" to their DNS queries. This will result in the desired FQDN format for your servers, such as "server1.DTC00.mpanynet.local" or "server2.DTC00.mpanynet.local".

Note: please do some tests in your lab, if everything is OK, you can try in your production environment.

I hope the information above is helpful.

If you have any question or concern, please feel free to let us know.

Hi

No my objective is not to have more than one fqdn for these servers.

My objective is when I will added a server on our domain for this site, the default fqdn for these servers are TC00.mpanynet.local (server1.TC00.mpanynet.local, server2.TC00.mpanynet.local, ...).

Hello JeromeCAR,

Thank you for your reply.

It seems you can not change the FQDN of the domain machine.

Here is a similar thread for your reference.
