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.

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
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.
For development purposes, I am trying to setup:
Azure Cloud: Virtual Machine with Windows Server 2019 acting as Domain Controller for Active Directory. machine also has DNS and DHCP.
VPN Point-To-Site so that local (physical) workstations can connect to Domain Controller
Join local (physical) workstations (Windows 10 Pro)to Active Directory domain.
Item 1 - done. I have up and running Windows Server 2019 with AD DC
Item 2 - done. From local machine (Windows 10 Pro) I can ping AD DC.
Item 2a - done. I have one Azure VM (Windows Server 2019) that can also ping AD DC.
Item 3 - not working. Local machine (Win 10Pro) can't join AD domain (addc.local).
Item 3a - working. Azure VM (WinSer 2019) join AD domain (addc.local).
I tried dozen of tutorials. Finally I (partially) succeeded with:
Windows Server 2019 – Active Directory Installation Beginners Guide - Success
How to install VPN on windows server 2019 - Fail. Can't establish VPN.
Azure - VPN Point to Site | Step By Step Tutorial - Success
Finally I got it up and running with 1 and 3.
Considering that Azure VM can join Active Directory, I think that AD DC is properly setup. Both machines belong to same VNET.
Considering that local machine can ping AD DC seams that VNET is properly setup.
What I don't get is why Azure VM can resolve and join 'addc.local' domain, while local machine can't.
On both machines, in network adapters preferred DNS is same: IP address of Domain Controller.
First question is why this doesn't work for local?
Second questions is this proper way to do it anyway (taking into account requirements)?
In this case, you may check the followings:
Usually the VPN client will inherit the DNS servers configured on the Azure VNet. If you have set the custom DNS server of the Azure VNet is the private IP address of the AD DC after you set up a client VPN connection. You could re-download your VPN client packages from the Azure portal. See this1 and this2 for more details.
Can you ping or nslookup the AD DC with its FQDN like dcVM.addc.local? If not, it might be a DNS issue. Read https://learn.microsoft.com/en-us/azure/virtual-network/virtual-networks-name-resolution-for-vms-and-role-instances#name-resolution-that-uses-your-own-dns-server
For best performance, when you are using Azure VMs as DNS servers, IPv6 should be disabled.
Not sure, but you could try this solution.
I am trying to connect an on-premises laptop with dynamic external IP to our Azure SQL Server. To do this, I created a virtual network gateway and connected the laptop to the gateway. Also, I added a private endpoint to the SQL server. After this, I can successfully connect to the SQL server IP using telnet, and if I resolve the SQL server FQDS in hosts file, I can connect to the server via SSMS. But without hosts file, the laptop always tries to connect to the SQL server via its public endpoint/address.
I found the following article: https://techcommunity.microsoft.com/t5/azure-database-support-blog/azure-sql-db-private-link-private-endpoint-connectivity/ba-p/1235573 The article is great. It recommends using your own DNS server to resolve the SQL server FQDN to the local IP. Unfortunately, the laptop does not have access to any custom DNS, so this solution does not suit.
There are two questions:
Is there any possibility to establish connection between an on-premises computer with dynamic IP and an Azure SQL server using a private endpoint but without own DNS server?
If the answer to the first question is "No", is there another way to connect an on-premises computer with dynamic IP to an Azure SQL server using any other Azure application(s)?
First of all, you can not use FQDN without DNS service. So you indeed need a custom DNS server in using FQDN of the server in connection strings for your clients to connect from on-premise VM to the Azure SQL server.
Since you are using a laptop, the DNS servers used by your computer are most likely specified by your ISP. You have no more control over it or ask your ISP to configure the DNS forwarder. Otherwise, you need to deploy a DNS server in your internal network. Currently, in this scenario, the best method is to use the HOSTS file on the local machine to override the Public DNS.
However, if you don't like using the HOSTS file, you can provision an Azure VM as the DNS server in the same Azure virtual network as the virtual network gateway.
Main steps:
Deploy an Azure VM, and RDP to that VM and run the PowerShell commands to install the DNS server role.
Install-WindowsFeature -Name DNS -IncludeManagementTools
Get-WindowsFeature *DNS*
Add Azure DNS (168.63.129.16) as a forwarder on your custom DNS server according to the step 5 in this blog. If you do not want to use forwarder you can also create a forward lookup zone and added manually the host to match the FQDN. You could read On-premises workloads using a DNS forwarder for more details.
After you have configured the DNS server and set the DNS forwarder. You could change the DNS server of Azure VNet to your Azure VM's private IP address.
Restart your Azure VM and re-download the VPN client package and re-connect the VPN connection to make the networking update. Check the DNS server on the local VPN client machine and set the DNS server to the custom DNS server in the TCP/IP settings. Then you will look up your private IP address via the default FQDN of Azure service.
In my example, I am using Azure storage account but it works the same with Azure
SQL database when using a private endpoint on the Azure and P2S VPN connection.
In this way, it requires that there are not any other VPN connections except the
P2S VPN connection on the local machine.
Then you could resolve the Azure SQL server FQDN to the private IP address of the private endpoint. However, it perhaps does not have a better performance to connect to Azure SQL Server with a VPN connection than directly connect to it through the public Internet and public DNS sevice.
I tried to configure a VPN with default values (10.0.1.x) with a point-to-site feature configured.
Azure Websites has been configured too, using the new Azure portal, to point to the Point-to-Site of the VPN.
When a try to contact SQL server of my VM in Azure (Iaas) fails, while locally on the VM I can do it.
I also configured an end point for the port 1433 on the VM with the relative firewall configuration.
Is there a way to check where is the issue using the website ?
Thanks a lot.
