We are planning on doing an Active Directory upgrade on our network. Currently we have a NetBIOS domain name of zxytest. We would like to change the NetBIOS domain name to abc. What is the best way to make the change? I am looking at TechNet articles and see that the NetBIOS domain can be changed. I think we have to do this before the upgrade. Another techie says that we can do this during the AD upgrade. I haven't seen anything on this though. I think he's getting NetBIOS and DNS names confused. Let me know if I am incorrect.
You cannot change the NetBIOS name of the domain during the upgrade. You must change is ahead of time -- see MS Knowledge Base article #178009, Renaming a domain: Process and side effects.
