can anyone help with some azure vm issues. I wished to connect a domain server VM and a ordinary server VM and use active directory synchronization. But every time I deploy new VM from azure portal, it always have the DNS name status as not configured. I really don't understand why. I set the DNS server with the private IPs of the VMs on the vNet. Thanks for replies and advise. VM DNS name not configured
As the comment stated, the DNS name for that VM is actually associated with the public IP attached to that VM. You can follow this step to create FQDN for an Azure VM.
If you want to join the Azure VM to your local domain, you can follow this link:
The main steps are as follows:
Establish cross-site connectivity using Azure site-to-site VPN connections
Configure a custom DNS server
Provision a VM with a custom DNS server
Join the Azure VM to the on-premises Active Directory domain
If you intend to join a Windows Server virtual machine to an Azure Active Directory Domain Services managed domain, read this tutorial.

dears I just bought a domain from Name cheap and I am using Azure VM Windows Server 2019 Datacenter, now I want to join my windows server on my domain to be as domain controller.
I add my IP address into the domain page, how I can join azure VM to the domain?
For joining the azure domain you need to configure S2S VPN (Site-to-Site VPN) between Azure and the domain and you need to configure your DNS manually to make sure that VM uses domain controller as its DNS server.
Here is the article to configure Site-to-Site VPN. you can create a new VNET or you can use the existing one if you have any. If you create a new VNET, you may need to re-create VM.
From here you can configure the DNS server manually.
And you can check this documentation for complete information
I have a Private AKS cluster deployed in a VNET on Azure. Once I deployed it, a private endpoint and a private DNS zone were created by default therefore making the cluster accessible from VM's which are part of the same VNET. (I have a VM deployed in the same VNET as the AKS cluster and "kubectl" commands work in it.)
My requirement is that I want to perform the "kubectl" commands from my local machine (connected to my home network) and also connected to the VPN which connects to the VNET.
My machine can talk to resources within the VNET but cannot seem to resolve the FQDN of the private cluster.
I read somewhere that having a DNS forwarder setup in the same VNET can help resolve the DNS queries made from the local machine which can then be resolved by Azure DNS. Is this the way to go about this? Or is there a better way to solve this problem?
It would really help if someone could give me an action plan to follow to solve this problem.
The better way to perform the "kubectl" commands from your local machine to your private AKS cluster is to use AKS Run Command (Preview). This feature allows you to remotely invoke commands in an AKS cluster through the AKS API. This feature provides an API that allows you to, for example, execute just-in-time commands from a remote laptop for a private cluster. Before using it, you need to enable the RunCommandPreview feature flag on your subscription and install aks-preview extension locally. However, there is a limitation that AKS-RunCommand does not work on clusters with AKS managed AAD and Private link enabled.
In this case, If you want to resolve the FQDN of the private cluster from your on-premise network, you could select to use either the hosts file locally(used for testing) or use your DNS forwarder to override the DNS resolution for a private link resource like this.
The DNS forwarder will be responsible for all the DNS queries via a server-level forwarder to the Azure-provided DNS 168.63.129.16.You can provision IaaS Windows VM with DNS role or Linux VM with bind configured as a DNS forwarder. This template shows how to create a DNS server that forwards queries to Azure's internal DNS servers for Linux VM. Refer to this for DNS forwarder on Windows VM.
If there is an internal DNS server in your on-premise network. The on-premises DNS solution needs to forward DNS traffic to Azure DNS via a conditional forwarder for your public DNS zones(e.g. {region}.azmk8s.io). The conditional forwarder references the DNS forwarder deployed in Azure. You could read this blog about DNS configuration sections for more details.
VM and App Service are located in the same Virtual Network.
App Service is added to VM through VNet Integration (preview)
VM is autoregistered in Private DNS zone, say by name myvm1. And full name myvm1.priv.zone
Private DNS zone is linked to Virtual Network.
Virtual Network - DNS Servers is set to default.
VM and App Service were restarted after configuration.
Problem is I can resolve neither myvm1 nor myvm1.priv.zone from App Service console by nameresolver.exe
UPDATE:
Actually, the issue is even bigger. App Service is not able to send requests to VMs in Virtual Network by their Private IPs (10.1.x.x) even if everything is allowed on VMs' subnet. If the same requests are sent to VMs' Public IPs there is no problem.
As the existing answer, for scenario Name resolution from App Service Web Apps to VMs in the same virtual network. in this DOC, you need to deploy your own DNS server to help name resolution.
Here are the steps:
On the Azure VM in the VNet, add a server role DNS server, after the installation, configure the DNS server, add Zone name such as qaz.lab in my example. You also can manually add an A record for your Azure VM in this Zone.
Add the DNS server private IP address in the custom DNS server of Azure VNet. Then restart the Azure VM to make it effective.
Configure VNet Integration with your app, in this case, select the new VNet integration. After that, refresh your VNet Integration. You will see the DNS server update in your app service plan --- networking.
Navigate your app service, run nameresolver FQDN to validate the DNS resolution. Currently, It only supports FQDN resolution.
Let me know if you have any question.
As of today, you need to use DNS proxies or forwarders to achieve your ask. It is documented here in the scenario table.
For scenario "Name resolution from App Service Web Apps to VMs in the same virtual network.", the solution is to "Customer-managed DNS servers forwarding queries between virtual networks for resolution by Azure (DNS proxy)."
On How to perform "Name resolution with your own DNS" check here, where your scenario is described.
I am trying to setup a custom build agent on a Windows VM in Azure. I installed the build agent from Azure Pipelines. The VM shows in the agent pool, but is offline. For this VM I used the default settings, so it automatically created a virtual network, public IP, and network security group. The network security group is modified to allow RDP traffic from my IP address only, and to allow HTTPS traffic. I am assuming something with this setup is preventing Azure Pipelines from sending data to the VM.
My first question is how do I get this setup to work. What am I missing?
My second question is how do I get this to work in a more secure way by removing the default link between the public IP and the VM, and ultimately blocking direct access to the VM with a firewall?
VM only needs outbound HTTPS access to Azure Devops
You dont need public ip for the agent vm

So I've created a VM Win Server 2016 on Azure. I've created a VPN connection between Azure VM (Which is AD DC) and a test windows machine. I can ping AD IP (but not domain, only IP), RDP into machine etc.. however when I try to join domain it's not recognized. So it's probably DNS issue on Azure but I've been unable to resolve it? What to do? How to proceed? The idea is to be able to connect remote machines via Point to Site VPN to AD DC on Azure.
Thanks
You need to have your DC listed as a DNS server if you are doing AD integrated DNS Or have a public record so that the Azure DNS servers can advertise it. Make sure you have done the step - Reset the DNS server for the Azure virtual network. You can also refer to http://msdn.microsoft.com/en-us/library/azure/jj156090.aspx for guidance and http://azure.microsoft.com/en-us/documentation/articles/virtual-networks-install-replica-active-directory-domain-controller/ for steps.
I've created a VPN connection between Azure VM (Which is AD DC) and a
test windows machine.
Could you please tell me which kind VPN do you deployed?
If you select S2S VPN, we can change the test windows machine's DNS to Azure VM's private IP address, then try to ping the domain name, if we can ping it, we can join this test vm to the AD DC.
If your VPN is P2S, we should change the test windows machine's DNS to the Azure VM P2S virtual IP address(get from p2s), then try to ping the domain name, and join to it.
