Rename on NETBIOS name ***only*** on AD

Hi,
I have seen this question asked numerous times on this forum but there is no direct answer.
I understand that there is procedure for renaming domain using rendom.

My question is only this.

Is it OKAY to change ONLY netbios name on domain and then change dns names through GPO?

I am trying to do this quickly and don't want to go through whole procedure for full rename or migration.

What would happen if I only changed netbios name under domain properties?

Not sure what the end goal is but another option may be to add another DNS alias name.

Hi Patrick,
Thanks for taking the time to answer. The end goal is basically to visually appear as a different name.

I plan to add another domain name to ad through group policy and change all dns suffix to that name.
Now, all I want is the netbios name to correspond to that new dns suffix, and not domain name. This is because when user is logging in to computer, Domain is shown as Netbios name.

Is it possible to change just netbios name w/out having to do complete rename procedure? what impact does that have?

Thanks.

How many domain controllers are there? The much simpler / safer method may be to stand up a new one with the correct computer name.

The two prerequisites to introducing the first 2019 or 2022 domain controller are that domain functional level needs to be 2008 or higher and older sysvol FRS replication needs to have been migrated to DFSR

I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting any operations. Then stand up the new 2019 or 2022, patch it fully, license it, join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to again verify health, when all is good you can decommission / demote old one.
