Task 1: configure basic settings

In the Basics page of the wizard, you can specify the DNS domain name for the managed domain. You can also choose the resource group and Azure location to which the managed domain should be deployed.

Configure basics

  1. Choose the DNS domain name for your managed domain.

    • The default domain name of the directory (with a .onmicrosoft.com suffix) is specified by default.

    • You can also type in a custom domain name. In this example, the custom domain name is contoso100.com.

      Warning

      The prefix of your specified domain name (for example, contoso100 in the contoso100.com domain name) must contain 15 or fewer characters. You cannot create a managed domain with a prefix longer than 15 characters.

  2. Ensure that the DNS domain name you have chosen for the managed domain does not already exist in the virtual network. Specifically, check whether:

    • You already have a domain with the same DNS domain name on the virtual network.

    • The virtual network where you plan to enable the managed domain has a VPN connection with your on-premises network. In this scenario, ensure you don't have a domain with the same DNS domain name on your on-premises network.

    • You have an existing cloud service with that name on the virtual network.

  3. Select the Azure Subscription in which you would like to create the managed domain.

  4. Select the Resource group to which the managed domain should belong. You can choose either the Create new or Use existing options to select the resource group.

  5. Choose the Azure Location in which the managed domain should be created. On the Network page of the wizard, you see only virtual networks that belong to the location you have selected.

  6. When you are done, click OK to move on to the Network page of the wizard.
