Re: Multiple PTR records wont go away in the reverse zone.

That was my take also. The team has some more concerns...

"Are you 100% sure that this is the behavior? I'm not seeing any
documentation about disabling DDNS being necessary. In fact, it sounds like
since the DHCP client is what updates DNS anyway, the DHCP server has rights
to delete any PTR records http://www.pcreview.co.uk/forums/thread-1470740.php

What about the DHCP setting "Dynamically update DNS A and PTR records only
if requested", so clients will specify.

I've been in global/mobile environments before, and have been pretty
successful with just leaving DNS settings at their defaults...

I do agree with all your DHCP server recommendations (especially entering
matching authentication information), but don't see DDNS updates being
necessary. Can you send me the document you're seeing that on? Or how
you're deciding this?"

Please could you give me your answers to his questions? Thanks.

Ok, this is the question my team posed when I shared this with them.

"All sounds good. Now please consider how disabling DDNS on DHCP
clients will affect these clients when they are roaming on external
broadband networks and need to get an IP address and possibly
register with DNS. Is that an issue? All laptops have to be able
to function correctly on and off the corporate network."

Actually, there is no other reason for a client to register in DNS when off
the corporate network. Any ISP that requires Dynamic updates, has certainly
configured their DHCP server to do the registrations because for the most
part, only newer windows clients register in DNS. I can almost guarantee
that these ISPs that require DDNS registrations are few and far between.
