As of October 2016 to join Windows 10 computers to Azure AD Domain service requires these steps: Create a VNET in the classic portal . The VNET must be placed to a region where Azure AD domain service is available (( https://azure.microsoft.com/en-us/regions/services/ ) In the classic portal go to Directory -> Configure and enable the domain service. And wait for ~ 30 min When completed the IP address will be populated Go back to the VNET configuration and add a DNS server with the IP (10.0.0.4 in this case) Create the "AAD DC Administrator" administrators group (again in Directory -> Group). Members of this group are granted administrative privileges on machines that are domain-joined to the Azure AD Domain Services managed domain. Add to the group your users who are supposed to have the administrative access on a Windows 10 computer go to Settings -> Accounts (this is true for Windows 10 version 1607) then select 'Access work
