Question regarding dynamic updates

[John Wobus]

I've been told that Microsoft's DNS server allows a zone to be updated
dynamically, yet some names in the zone be protected from changes via
dynamic updates.  And I was told that BIND lacks this feature, having 
its granularity of
control strictly by zone.  I would assume Microsoft's GUI makes this 
simple to manage,
:-) but the mechanism would be functionally like having a list of names 
stored somewhere
that the dynamic update mechanism would refuse to modify in the zone 
file.
