Are we talking Windows or Linux clients here ?
If Linux, then I am surprised that their DNS records are getting
updated in AD at all, as far as I am aware, there isn't any mechanism
to do this.
Windows clients are different, they can and do update their own AD DNS
records, whilst this might not be instantaneous, it isn't really long
either.

Windows clients
Sometimes it's not long and happens eventually but sometimes it's been
hours since the computer was booted and the DNS records still point to
their previous IP address and I have to go look for their current IP
address on the router's status page to connect via RDP to them
Hmph. So I'm at Microsoft's mercy here? Is there not a way to run a DHCP
server on the samba DC and have that instantly update DNS records instead
of waiting for the client computers to do it when they want?
