Dynamic Update of A&PTR Records - Best Practice?

Hi,

I'm looking for some advice on the pros/cons of turning on the option within
the DHCP Server that says "Always Dynamically Update A & PTR Records".

We run a Windows 2003 AD network with a DC running DHCP and DNS. On the
workstation we have Windows XP Professional.

I understand that Windows XP clients, by default, automatically update their
DNS A record when renewing IP address allocations from DHCP, but not PTR
records.

Is there any reason why you would not turn on this option, so that PTR
records are kept upto date without manual intervention?

I'm interested to understand the reasoning behind turning on/off this
option - whether it's a case of needing it when you use legacy clients that
don't automatically update records in DNS, or some other valid reason.
Thanks for any assistance offered!

Regards,

Richard Tubb.
