Thanks for your continued assistance...

Is there a way to force the [WinXP] clients to update their A/PTR
records directly with the AD/DNS server?

Well, yes, assuming you mean for DHCP clients. Non-DHCP clients do it
anyway. In DHCP properties, under the DNS tab, check the appropriate boxes.
But it is your benefit to force Windows DHCP to do it, as well as giving
DHCP ownership of the record (by adding the DHCP server to the
DnsUpdateProxy group). This way you won't find dupes of the same hostnames
with different IPs. This plus setting scavenging in Windows DNS, will
automate self-cleaning, so to speak. If you want to do this, follow the
instructions concerning the DnsProxyUpdate group. Matter of fact, this is
good reading concerning how the whole process between Windows DNS and
Windows DHCP works:

While I appreciate the win of using AD/DNS and AD/DHCP, it's not
something I'm going to be able to implement in our environment.

I can understand.


If the clients do own the A/PTR records and can directly update
AD/DNS, can the "stale" records be removed manually or by using
scavenging?

Scavenging.


I will definitely incorporate your recommendation of using a forward
to the BIND/DNS server to minimize the exposure of the AD/DNS servers
to the Internet.
