This Post will show you how to deploy a Remote desktop session server (RDSH) in a workgroup (non Domain). Credit: ryanmangansitblog.com
This deployment is Session based and will allow the use of desktop sessions. The down side to having a none domain joined Session host is that you will need to create users on the host and configure local Group policy’s to restrict user access.
I have deployed a single server (non domain Joined) with Server 2012 R2.
Configuring the FQDN
As this is a workgroup server (non Domain) you will need to configure the Fully Qualified Domain name.
This can be done under system Properites
Deployment
We are going to deploy the RDS 2012 Session Host Role and the RDS licencing role
This image shows the roles and features that have been installed, as you can see the session host and remote desktop roles are shown as installed.
Next you'll need to setup the server to validate the volume licenses against itself... to do that, read this article.
