Installing RDS on Windows Server 2012 without AD
Solution 1:
Actually, one can install RDSH on Windows Server 2012 in a Workgroup environment.
This configuration is appropriate when there is only one server on the network and it will provide desktop sessions to users based on the number of Remote Desktop Services client access license (RDS CALs) installed on the server, but will not provide access to RemoteApp programs or the RDWeb site.
You should install two RDS roles:
- Remote Desktop Licensing
- Remote Desktop Session Host.
Then install RDS CALs (either per user or per device).
The last step would be to configure the Remote Desktop Session Host role to use the local Remote Desktop Licensing server.

Seems like MS have changed it in 2012, so you cannot install RDSH standalone in a workgroup :(

Solution 3:
If you are doing a scenario-based deployment, all affected servers need to be in the same domain. This will not work in a workgroup.
I must admit I have not tried installing the roles individually and configuring them manually. This may not work anymore ...
