Dhcp not updating dns windows 2018 r2

Rated 4.97/5 based on 606 customer reviews

I'm attempting to replace Windows Server DHCP with ISC DHCP.

In order to do so, I need to be able to facilitate updating DNS records from clients that do and do not support dynamic DNS record registration.

This is for an Domain User who is a member of the "Dns Update Proxy" in Active Directory.

You should be able to do this on Windows or Linux (but the keytab must be copied to the server running ISC DHCP).

You can validate this via the DNS MMC on Windows and checking the Security tab of the A/AAAA record in question.

I'm using Boot Device Manager to assign the IP addresses.

I’m not sure how often that bind rewrites these files, but at least it seems to always happen when you stop the bind service.

What I think is more important is to always stop the bind service before making any changes to the database files, otherwise they might be overwritten by bind.

If you have followed the steps in my previous post you might have your zone database files in /etc/bind/zones.

We will start by copying the files so we have a backup remaining if anything goes wrong: 1.1 Copy the zone database files: We now need to add the key to the bind configuration and tell it what zones that we want it to allow updates on.
