Azure AD Domain Join error code 0x0000232B RCODE_NAME_ERROR

Question

Just setup a new Azure AD subscription associated with our Azure AD. Deployed a new Windows Server 2019 Data Center VM and whenever I attempt to join the VM to our domain (which I can ping by name from a command prompt) I get the following error:

(domain name and IP changed for posting)

The error was: "DNS name does not exist." (error code 0x0000232B RCODE_NAME_ERROR) The query was for the SRV record for _ldap._tcp.dc._msdcs.ourdomain.com Common causes of this error include the following: - The DNS SRV records required to locate a AD DC for the domain are not registered in DNS. These records are registered with a DNS server automatically when a AD DC is added to a domain. They are updated by the AD DC at set intervals. This computer is configured to use DNS servers with the following IP addresses: 1.2.3.4 - One or more of the following zones do not include delegation to its child zone: ourdomain.com com . (the root zone)

The VNET has the Azure Active Directory Service Endpoint enabled so I would expect the DNS Server to have the required DNS SRV records needed for this.

What am I missing here? Thanks!

Hello @SandBox-3325

This error usually occur if the computer that you want to join to the domain is not able to resolve the domain name. Please try to configure the IP addresses of Azure AD Domain Services object as DNS server address in the V-Net. You can find the IP Address in the overview blade of the Network Interfaces created for Azure AD Domain Services and in properties of Azure AD Domain Services object as well.
