Hello,
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.
