A lot of companies use their own Top Level Domain Names in their internal networks for resolving internal services. As an example, I would mention the .intel
TLD.
I'm doing something similar in my homelab. For the purposes of this post, let it be .example
.
I would like to set up an Active Directory server for user authentication and DNS management. Here's my problem: when I want to promote the Windows Server to a Domain Controller, it asks for a Root forest domain. When I type in example
, the following error occurs:
Verification of forest name failed. The DNS name "example"
proposed for this Active Directory domain consists of single label.
DNS domain names should be unique and fully qualified,
consisting of one or more labels separated by a period ("."),
followed by a top level domain.

I have also tried typing in .example
but the error still persists.
Is there any registry tweak, that I need to make to skip this check?
