@nerdydad That's not for the user. That's for the admin who then delivers that via whatever management solution they use.
Quick Access/Favorites can be Group Policy managed so all or some domain members can get it easily.
For external users it's a two step process to send them a shortcut and they know how to log on from there.
There are 4 RDP servers, brokered together for our ERP system, along with all of the off-chutes that some users will have with some other servers for whatever reason, plus their desktop, for 130 users.
I find the most difficult part of managing an RDP farm is getting the apps themselves to play nicely. I've only had a couple of apps that just flat out refused to work correctly.
Since this is all virtualized, I'll just take one server, sysprep it, shut it down, and then just clone it. Apps are all the exact same. The only thing that needs to change are the UUID's and the database.
