I'm a bit confused here. What DNS backend are you using? As far as I can 
tell, the "allow dns updates" directive in smb.conf is only used by the 
internal dns. Yet, in the other thread you mentioned you were using BIND 

With the internal DNS, as long as the appropriate subnet is created in 
AD, clients should be able to make updates to that subnet. If this is 
your scenario and it's not working, please let me know.
