You can make the NetBIOS domain name anything you want. but keep in mind
each AD domain must have its own NetBIOS name, you cannot have one NetBIOS
name for the entire enterprise if each part of the enterprise will have its
own domain.
NetBIOS domain names can no longer use a DNS style name, I'm not sure if
that changed in Win2k or Win2k3. My Win2k domain has a DNS style NetBIOS
name, but it was upgraded from NT4.
Here a while back, I tried to assign a DNS style name to a Win2k3 domain and
it would not let me.
All this being said now, you can set this up in a single domain model, using
OUs with each location having its own Primary DNS suffix. But that could get
more complicated than using child domains.
