Unable to add 2nd PC to the Domain controller(PC1) both are Azure VM's

Question

Hello Community,

I have created two Azure VM's, VM1 installed with windows 2019 datacenter and successfully promoted as DC.

VM2 installed with same server and when i try to add the VM2 to VM1, received below error.

Note: This information is intended for a network administrator.

If you are not your network's administrator, notify the administrator that you received this information, which has been recorded in the file C:\Windows\debug\dcdiag.txt.

The following error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller (AD DC) for domain "domain name":

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.domain name

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:

168.63.129.16

• One or more of the following zones do not include delegation to its child zone:

domain name

com

. (the root

I can ping VM1 from VM2,

By default, VM2 assigned with following DNS address "168.63.129.16 ", when i add google dns(8.8.8.8 and 8.8.4.4). Unable to ping VM1 from VM2.

tried with different version, still same.

Kindly advise,

Answer 1

Make sure the domain controller and all members have the static address of DC listed for DNS and no others such as router or public DNS.

Hello Patrick,

Thank you for the update.

I have updated VM1 private IP address as a DNS address in Vnet. So then i can perform domain join.
