I also have objects out of sync that were in sync prior to updating.  
All DCs are running 4.7.0.  There are duplicate members in some groups 
too.  When I try to remove all members from one of these affected groups 
I get "The following Active Directory Domain Services error occurred: 
The environment is incorrect."

Thanks,
Arthur
