Is dynamic DNS support absolutely /necessary/?  I.e., will a W2K DC fail
to provide services correctly if it can't register the DNS name, in the
same way than an NT PDC can be DoS'ed if there is already a PDC
registered with the WINS server?  I'm personally not particularly keen
on the idea of configuring dynDNS support just for AD -- though happily,
I'm pretty sure I can count on this not being a requirement for Samba
