Will your DHCP server be the one to register the clients DNS names and 
IP's? If so I vote to go with Bind. It's not difficult to switch between 
the internal and Bind if you want to change in the future.

As far as clients not associated to the domain and registering their 
IP's and names. Not sure if the DHCP server can be authoritative for 
them. In the past I have used the internal and let the clients update 
their own IP's and names with nonsecure DNS updates. I would advise 
against it though.
