Using the info on this TechNet page, I've successfully established a remote PowerShell session with a 2016 Preview 2 Nano Server running in a Hyper-V VM.
I now want to add the SMTP Server role. I was expecting this to be a trivial matter, as we are given to understand Nano Server is the future of Windows Server and will do everything we're used to from Windows Server, except that it's "headless", i.e., can only be managed remotely, which is done via WMI and PowerShell.
However, it seems roles and features aren't added in the traditional way, using PowerShell cmdlets such as Add-WindowsFeature, but rather by using dism to add Packages to the VHD image. Okay, but there are only about five Packages, which don't include SMTP Server. Only things to do with Hyper-V, Failover Clustering, Networking, and File Server role.
I did try Add-WindowsFeature and suchlike in the remote PowerShell session, but it didn't recognize any of the usual cmdlet names. I suspect this is more than just the cmdlets not being present.
Perhaps this is just a limitation of the pre-release Nano Server? But I couldn't find any statement to that effect.
Is it possible to add the SMTP Server role in Nano Server?
EDIT: here is the output from Get-WindowsFeature:
PS C:\Users\Administrator\Documents> Get-WindowsFeature
Command 'Get-WindowsFeature' cannot be found.
...and from Get-Module:
PS C:\Users\Administrator\Documents> get-module -listavailable
Directory: C:\windows\system32\windowspowershell\v1.0\Modules
