How to add a new DC in an existing domain when there is no Windows DNS Server?
Hi, We have an AD Domain Controller which uses a linux-based DNS servers. We now need to add a new DC in this existing domain. The problem is when I try to add this new DC I have the following mes...
You should be able to simply add the windows domain controller without integrated DNS role.

No, you don't need to use Microsoft DNS for ADDS (though I would highly recommend it).
You can use BIND or another third-party DNS-Service for ADDS, as long as it supports the needed entry types (SRV for example).
You can read more about it here:

This should put you on the right track.
Personally, if you really want to do this, I would first check that the current BIND-Zone for ADDS really contains all needed entries (and they are correct), and then try to configure dynamic DNS-Updates for your BIND-Servers.
If you can't configure dynamic DNS-Updates for your BIND, you have to create all needed DNS-entries manually.
That said, you will still have problems integrating other software which relies heavily on ADDS (for example Exchange Server), and should migrate to a Microsoft DNS solution as soon as you can.

Thank you for answering. I think I was not specific enough:
- We have a domain (that we will call domainA.net)
- We have a domain controller running Windows Server 2019 hosting this domain
- This domain controller DOES NOT hold the DNS role
- The DNS system used to create this domain is a BIND DNS
- the domain is registered to the BIND DNS system
- I need to add a new domain controller to the domainA.net domain
This is where it gets tricky:
- this new DC MUST NOT hold a DNS role
- when I try to add this new DC to the domainA.net domain, it fails because of the following error: "An Active Directory domain controller for the "domainA.net" domain could not be contacted.
A nslookup command finds my domain. I can also ping it successfully.
Any other idea?
thank you for reading and helping.
