Change the DNS registration behavior of the DHCP Client

[Guest]

Hello,

I already posted ths question in the DNS Server forum, but didn't get an
answser.
I want Windows 2000/XP clients which are using DHCP to tell the DHCP Server
that the DHCP server should register the A and PTR record in DNS on behalf of
the client.
To negotiate the dynamic update process, the DHCP client sends its FQDN to
the DHCP server in the DHCPREQUEST packet by using the FQDN option. The
server then replies to the DHCP client by sending a DHCP acknowledgment
(DHCPACK) message by using the FQDN option. See below (DHCPREQUEST).
On default the DHCP Client sends Flag 0 (Client wants update A record,
requests the server to update PTR record) to the DHCP server.

How can I change this behavior of the DHCP client. I would like the DHCP
client to send always Flag 1 (request the server to update A and PTR record).
Is there a
registry key to do this?

P.S.: I don't want to change the settings on the DHCP server and the client
must use DHCP.

DHCPREQUEST

Code: Specifies the code for this option (81).

Len:
Specifies the length of this option (minimum of 4).

Flags:
Can be one of the following values:
0. Client wants to register the A resource record and requests that the
server update the PTR resource record.
1. Client wants server to register the A and PTR resource records.
3. DHCP server registers the A and PTR resource records regardless of the
request of the client.

RCODE1 and RCODE 2:
The DHCP server uses these fields to specify the response code from an A
resource record registration performed on the client's behalf and to indicate
whether it attempted the update before sending DHCPACK.

Domain Name: Specifies the FQDN of the client.

Kind of lost me on this one: "I don't want to change the settings on the
DHCP server"

Is the DHCP server DNS tab set to Always update DNS? See:

The point is , we want that Windows 2000/XP Clients which are not a member of
our Active Directory register their DNS records in a secure active directory
zone.
Because those clients are mixed up with Active Directory clients in the same
subnets we can't change the behavior of DHCP unless all clients will be
registered by the DHCP srerver. That is not our intension. So we will have to
use reservations for the non-ad clients and change the DNS settings there,
but that is not very flexible. If a client is moved to another subnet we will
have to create a new reservation. Therefore we are looking for a setting that
changes the behavior of the dhcp client. I.E. HP printer boxes request the
DHCP server to update both records, A and PTR.
