In the DHCP Log I see 31 Dynamic Update Failed. Like I said I attempted
to
use credentials already, but just to be sure, what groups does the user I
use
need to be a member of? I am guessing DNSUpdateProxy, anything else?

Generally nothing special.

Definitely not DNSUpdateProxy which is an ALTERNATIVE
(and less secure) than specific credentials.

A regualar account should be perfectly usuable and is only
an issue if you have multiple DHCP servers which would
otherwise fight over ownership fo the DNS records when
using Secure updates.

"Then likely you have trouble with your (possibly missing)
REVERSE zone." - The reverse Zones are present and set correctly. We
have
multiple Reverse zones: 0.0.10.in-addr.arpa, 0.1.10.in-addr.arpa,
0.100.10.in-addr.arpa, etc.

Can we assume you use 10.100.0.0 or 10.100.1.0 addresses?

"The DNS server for your clients must either HOLD the reverse
zone OR be able to find the (master) DNS server which does --
same rule as for forward zones." - This is on the primary DNS Server.

I did not create the reverse zone, I do not know who did, I am
inheritting
it. It is set to Dynamic Updates Nonsecure and Secure. A strange
thing,
we
have around 400 clients, there are PTR records for Clients that are not
DHCP
(Mostly servers), DHCP clients do not have a PTR record.

Ok, then you have the Reverse Zone, it's on the same server
the clients are using (and thus reachable), and it is dynamic.

After that there is no likely reason the DHCP server cannot
register the clients SINCE it is already registering the Forward
records.

You might double check that the DHCP server is set to make
the registrations but surely you have done that by now since
you were knowledgeable enough to know of the existence of
"credentials"

BTW, those credentials are only needed for SECURE updates
but are a good idea for that.

Herb,
I do not understand the questions.

Then likely you have trouble with your (possibly missing)
REVERSE zone.

Did you create the reverse zone?
The zones are set on the DNS server.

You have a zone for the FORWARD (name zone) such as
yourDomain.com but did you create the REVERSE zone
that maps IP to names?

This would look like "168.192.in-addr.arpa" depending on
the actual IP range.

Is the reverse zone set to be dynamic?

If you have that reverse zone, it is TOTALLY unrelated to
the forward zone so you have to use the REVERSE zones
properties to make it DYNAMIC just as you would a forward
zone.

Is the reverse zone discoverable by the DNS server
the clients and DHCP server are using?

The DNS server for your clients must either HOLD the reverse
zone OR be able to find the (master) DNS server which does --
same rule as for forward zones.

If the answers to the above are all yes (or fixing them
doesn't solve the problem) then please describe how
your REVERSE zones are set (where, which DNS server,
how the DHCP is related to them, etc.)

You wrote "the zones are setup" -- Which zones, give all of
the names and tell us which DNS holds them, and whether they
are DYNAMIC (in properties.)

DHCP is set to dynamically update. For each of my clients DHCP is
creating
an A record in the forward lookup zone however it is not creating a
PTR
record in the reverse lookup zone.

So did YOU create the REVERSE ZONE? Is the reverse zone dynamic?

We do not have any PTR Records being added Dynamically in DNS,
the A
records
are being added. DHCP is running on a DC. I have tried
specifying
user
credentials for Dynamic Updates but it did not work.
