     To access an Azure file share by using Azure AD credentials from a VM, your VM must be domain-joined to Azure AD DS. For more information about how to domain-join a VM, see [Join a Windows Server virtual machine to a managed domain](../../active-directory-domain-services/join-windows-vm.md). Azure AD DS authentication over SMB with Azure file shares is supported only on Azure VMs running on OS versions above Windows 7 or Windows Server 2008 R2.

+## Mount the file share from a non-domain-joined VM

+Non-domain-joined VMs can access Azure file shares using Azure AD DS authentication only if the VM has line-of-sight to the domain controllers for Azure AD DS, which are located in Azure. This usually requires setting up a site-to-site or point-to-site VPN to allow this connectivity. The user accessing the file share must have an identity and credentials (an Azure AD identity synced from Azure AD to Azure AD DS) in the Azure AD DS managed domain.
+
+When mounting the file share, the user must provide explicit credentials such as **DOMAINNAME\username** where DOMAINNAME is the Azure AD DS domain and username is the identity’s user name in Azure AD DS. This will help route Kerberos ticket requests from the client to the correct domain controller in the Azure AD DS domain.
