I recall back in the Terminal Services days that you wouldn't enable TS application mode on your business application servers just so that a team of devs/admins can RDP to the application server (i.e more than 2 RDP sessions required). Since it does things to Windows and changes the way the apps run.
Note that I'm referring to a server that hosts a business application eg JBoss application server hosting a web application. Not referring to a server for hosting remote apps (MS Office), or used as a jumpbox etc.
I'm trying to find advice on whether this is still the case with Windows 2012 R2 RDS. Searching for these terms only brings up sites for installing RDS.
The development team at my work are requesting more RDP sessions to their server environment and are asking about installing RDS on the servers. I know about the virtues of RSAT and remote deployments, but I was also curious if it will change the way the OS behaves.
