Change domain NetBIOS name

Posted on 2004-04-28
Last Modified: 2007-12-19
We have an 2003 native AD domain with an empty root and two child domains (New York and London). The dns naming convention for these domains is fine, but the old NetBIOS names are inconsistent with our setup, as they were created many years ago. I would like to change these domain names, and I was wondering what the impact would be. I have not yet raised the functional level of the forest or any domain.

Thanks, I have actually already seen this article, and the associated MS documents. It goes into depth about renaming domain dns names, but does not really explain NetBIOS only renaming.

But the Windows Server 2003 Active Directory Domain Rename Tools only works for mixed mode domains and yours is already native mode. so you can't rename.

But I thought that was the only way you COULD rename a domain - by becoming 2003 native and raising the domain functional level?

it is only native with the functional levels raised that you can do this
do you have exchange installed in the environment?

Yes, currently 5.5 on a 2000 server. I am in the process of building a new 2003 machine to migrate the users to. Would it be better to wait until I have done this?

the documentation indicates that you cannot make this change after you implement Exchange in active directory (e2k or e2k3), so i would wait till you are satisfied with the name before you make this move
