So, editing config files on each of them is not an option (we will come to this later).This is the simplest and most reliable solution of the available options.

But the nature of these devices is different from Windows based clients that they mostly rely on outbound connection to internet.

The problem is that, in such setup the DHCP server becomes the owner of the A and PTR records (see below).

It is fine as long as the DHCP server is alive to create and remove records.

Selecting the second option forces DHCP server to update A record as well.

But the prerequisite is that the client should request for DNS update.

The client is expected to send a transaction signature along with the update request.

There are different types of signatures such as a TSIG resource or the SIG(0) or GSS-TSIG signatures.

Every time a Windows PC gets an IP address from DHCP server, it would send a DNS Update (Opcode = 5) request to its registered DNS server.

Performed manually, this is same as typing “ipconfig /registerdns” at an elevated command prompt.

Take a look at the capture of Linux client performing DNS update, you can see that the server comes back with a UPDATE REFUSED response.

This is because our DNS server is enabled with secure updates which means only authenticated clients can send update.

I wonder if a Windows Domain DNS Server should register any Domain Member in general?
