Improved domain joining functionality
Coming from a background with Altiris DS 6.9, which had a very simple and seamless gui-based feature built in that you could use to rename a machine and join it to a domain, I think it would be incredibly useful to have a pre-cooked rename and domain-join script that provided you typeable fields for your domain info, credentials, machine name, etc. Ideally it would function with a 'run now' option to work immediately.
In environments where machine names must change relatively frequently, the k1000 struggles

Coming from an Altiris 6.9 history how is it that 10 years on we have gone backward in all of the major deployment apps.
