If I have a domain : corporate.com

With 3 subdomains :

• dev.corporate.com
• voice.corporate.com
• vpn.corporate.com

How can I delete the top domain, but keep the 3 child zones?

Specifically for Windows DNS, this would look something like this :

I suspect there is no easy way to do this, which means I manually have to edit the entire zone file to end up with 3 separate zone files for the child zones. But I'm hoping I'm wrong. Any ideas?

I have an environment where Active Directory Domain Controllers host their own DNS domains (as is common).

However we are trying to separate DNS and host it on a standalone server (to eventually move to Linux Bind, but for now just the decoupling)

I have tested this in a lab environment but can't get the decoupling to work.

Step One - Basic Setup

• Create an AD zone "mylab.com"
• Add a domain controller "server1.mylab.com"
• AD can update the domain perfectly fine

Step Two - Move out DNS zone

• Backup and delete the entire zone "mylab.com"
• Create a Conditional Forwarder for "mylab.com" pointing to standalone DNS server
• Manually create a new zone "mylab.com" on the standalone DNS server
• Allow Insecure Updates on the standalone server (On Bind it would be 'allow-update ACL')

Step Three - Test DNS Updates from AD to Standalone

• Restart NetLogon Service

this should trigger the DC to create all the AD related DNS records on "mylab.com" hosted on the new Standalone DNS server.

but I don't see any attempts of DNS updates on the standalone DNS server logs.

I do see DNS queries coming in from the DC, but no updates)

Unikernels are a new thing and I am having trouble understanding what their use cases are.

Any use case I can think of is already served by the existence of Docker Containers.

So what are Unikernels meant to be used for?
