RDS on windows 2012

Server 2012 R2.
Need to install Remote desktop services in an eval mode for just one 3rd party app with printing ability.   User's will use Remote desktop client to log into the 3rd party app and run the application.
(I'm leaning towards the role based...but wanted to ask the experts for their opinions).
1. Need some info to decide weather to install it using the traditional "ROLE BASED" Installation or use the remote desktop services-scenario based installation.  
2. I assume the eval mode will allow me 120 days to test this out.  does that work in either installation?

Always use scenario based.  Role based would only ever be used in very special edge-case scenarios and those who need it wouldn't need to ask...  ;)

Eval mode will apply to either installation, but don't wait the full time that you have or you can find yourself in an ugly situation because of how RDS handles things when the eval runs out (deleting registry keys, having to uninstall and reinstall components...not good.)   If you know this is the way you are going to go, just do it now.  If not, test it, but as soon as you are comfortable, buy the licenses (10-15 days.)  Yes, you have longer, but you'd be shocked how often I get called to clean up a mess (and how much I can charge for it) because the IT person procrastinated.  If you are looking to use the eval mode just as a temporary solution, *THAT* is actually illegal (you aren't evaluating for a potential purchase) and you still have the bad side-effects to the server and installed applications  that will occur when you go to uninstall the role.  

Mind you, I make no assumptions on your intention, so I tried to cover all the bases on the things, good, bad, illegal, or just "other," that I've seen.

:)   Thanks for the assistance---Yep, I'm having them try it in the eval mode for a few days to make sure it works with the 3rd part app. once we know that it works and works well---I plan on purchasing a 15 user license.  

So, if we go scenario based, can they still access it using remote desktop client   or will they only access it via a web interface?
any good article for scenario based install?

Also, to note: its on a single server that currently has AD on it.

You *can* still access RDS by opening the RDC directly, but that isn't the recommended way anymore.  You should use the web interface (even with the role-based approach.)  All the web interface does is send an .rdp file to the client machine and whatever program is associated with .rdp will open and process the file.  So in most windows machines, you'd still end up connecting via RDC.  But by using the web interface, you no longer have to tell users what servers to connect to, what settings to check and uncheck, and you can make changes in the background without needing to redeploy or re-educate users.  That's a *huge* benefit to using the web interface.  And that works with both role-based and scenario-based installations.

As far as a good article, the RDS team just published a series of good blog posts. A quick search via TechNet will turn up plenty of good info.

It has been a very bad idea to install RDS (or TS) on a domain controller since 2000.  2003 was worse.  2008 and 2008 R2 was almost impossible to get things working right.  2012 blocked it when it shipped. They've later backtracked and it is no longer blocked (primarily for political reasons), but it still rarely works right.  I can't recommend that under any circumstances. 2012 and 2012 R2 standard comes with 1+2 virtualization rights, so you can run 2 VMs if you need this.  There is never a good reason to install RDS on a DC with those licensing rights.
