MicrosoftDeleted Windows Servers do not have MDM stack so at present they cannot be managed by Endpoint Manager in the cloud. I would recommend taking a look at Azure Management Services - https://docs.microsoft.com/en-us/azure/governance/azure-management.
Ahmedtameem, Kelvin Papp Once you enable this capability on an Azure IaaS Windows VM, then the VM is Azure AD joined. You cannot then promote it to a DC or join to any other AD or Azure AD DS domain. If you need policy management, I would recommend you to take a look at the different services offered by Azure Management Services - https://docs.microsoft.com/en-us/azure/governance/azure-management. Additionally, this capability does not supersede on a VM that is joined to AD/Azure AD DS.
Jasper Kraak We are working with Windows on this and it will take sometime to support other configurations and extend this to non Windows platforms too.
bel_from_nz We are working with Azure Networking team to determine how to best integrate this capability with Azure BAstion Service. Expect more details on this sometime next year.
airliner We have added support in the next release of Windows to allow an Azure AD Registered Windows 10 client to RDP to an Azure AD join target machine. This will allow you to add additional work or school accounts on you Windows 10 PC for each of the customer tenants you manage and then use the respective account to connect over RDP to your target Azure AD joined machine. You can verify this using any of our latest Windows 10 Insider Build https://insider.windows.com/en-us/.
