I have (please don't laugh!!) an old early 90s DOS application at my place of work that I'm serving up via RDS / Terminal Services from a 32-bit install of Win 2008 Server. Using first gen RemoteApp technology, it actually works surprisingly well. We use RDS purely for this one app.
Through a long and boring story, I've realised we aren't licensed with RDS / TS Client Access Licenses. I want to get the right number of CALs, but it is unclear the number of licenses I need to get for our scenario.
To be clear, whilst the users who connect in have their own AD User Account running on their local PC, the user account used for the remote app is exactly the same from each different system. So, whilst one user might initially log in to their workstation as 'mike.webb' and another as 'tom.smith', both then use the AD username 'old.dos' to fire up the RemoteApp.
We have a total of 15 users doing this. Do I need a RDS User CAL for each user loging in initially, or do I need only 1 RDS CAL, as I'm using an identical user name to connect to each instance of the software on the RDS Server?
Any thoughts would be greatly appreciated! Microsoft have been unable to answer this one. I've included Citrix as a relevant topic, as I know RDS has some historical rooting in this, and hope you guys might help.
