The virtual network that you use for Horizon Cloud node must have the ability to resolve both internal machine names and external names. During and after the node deployment process, the Horizon Cloud node needs the ability to resolve external names. The ability to resolve internal virtual machine (VM) names is needed for the node's Horizon Cloud Active Directory domain-join operations with the VMs that get deployed in your Microsoft Azure environment.

About this task

In a Microsoft Azure subscription, internal network connectivity is not set up by default. For production environments, you would typically configure the virtual network's DNS settings to point at a valid DNS server that can resolve external names as well as work in Microsoft Azure for your corporate machines. For example, you might want to deploy a Microsoft Windows Server 2016 virtual machine in that virtual network to act as the DNS server, and configure the virtual network's DNS setting to point to the IP address of that deployed DNS server.

For proof-of-concept environments, if your organization's privacy and security policies allow, you can configure the internal DNS to delegate to an external public DNS for external name resolution. Some organizations and ISPs provide public recursive name servers to use for such purposes, such as OpenDNS at or Google Public DNS at For a sample list of public recursive name servers, see the Wikipedia article Public recursive name server.


Ensure your Microsoft Azure region has the virtual network that you plan to use for your node. See Configure the Required Virtual Network in Microsoft Azure


  1. From the Microsoft Azure portal's left navigation bar, click Microsoft Azure Virtual Networks menu item in the Microsoft Azure portal's main menu (Virtual networks) and then click the virtual network that you are going to use for your node.
  2. Display the virtual network's DNS server settings by clicking DNS servers.
