Why is my Centos Customization Profile prompting for a NetBIOS name?

I am trying to create a CentOS customization profile:

In the next step, the wizard is requiring a NetBIOS name:

If I continue, and enter the unqualified hostname for the NetBIOS name, and enter IP addresses etc, I

end up with a non functional VM with no network settings.

I don't see the NetBIOS name as anything I can edit in the Policies and Profiles, Customization Spec Manager dialogs.

Anybody see this? Is there a workaround? Are Linux Customization Specs broken in our version: "Version 6.5.0 Build 5705665"?

Thanks
