Hi, Please provide complete details on the query are you looking to join the Windows Server to Azure AD Directly or Hybrid? Hybrid will require AAD Connect Tool - [https://learn.microsoft.com/en-us/entra/identity/hybrid/connect/how-to-connect-install-prerequisites]
Or Entra Managed Domain Services https://learn.microsoft.com/en-us/entra/identity/domain-services/
Hope this helps. JS
