Domain change

I have a script that will do what you're asking.

It will:

-- Rename the system in the format of (userinitals)-(last8ofthesystemSN)-(modelcode)
-- Unbind from the "old domain" and bind to the new domain -- Not touch any systems bound to the new domain
-- Bind any system not bound to a domain to your new domain
-- I also have the flags set to enable mobile users but not prompt the user.
