There is no way to tell, however if the application hahs been installed AFTER the Remote Desktop Services role was added then it will be installed for use with Terminal Services/Remote Desktop

Commented:
Depends, normally the idea is that installing in install mode creates different registry hyves for each and every user for that application. If an application is Terminal Server aware it will do so by itself (settings that an application declares in HKLM can be overwritten if different users work with it) and you won;t be able to see how it is installed.

Also, did you install using add/Remove programs? Using this way the server automaticallty switches modes..

No there is no way to tell to be safe you can remove the application then re-add through the TS install mode if you want to make sure. Another way to tell which isn't 100% is that if mulitple users are working on the application through RDS without errors most likely it was installed properly.

I am coming into this after the fact (the life of a consultant).  There are some indications that not all is well with the RDS server.  Also, one of the application installers was commenting on how you didn't need to go into install mode anymore to install applications on RDS.  When he saw how that tweaked my attention he later denied saying it.  

If I understand the responses here correctly, there is no neat little app which says all is well/not well.  I can look at registry keys or I can research the apps that were installed and find out if they are RDS aware (DynamicsGP).

Correct there is not a tool but if the app is complaining then you would need to uninstall then install the properly way
I would assume on 2008 the same mechanism previously used is still in place. When an application is installed on the system using 'CHANGE USER /INSTALL' or the Control Panel | Add/Remove Programs it tracks the install under the TS shadow key.

The answer is accurate and is disappointing at the same time.  For Microsoft to not provide a good way to find out a complete list of installed apps for Remote Desktop Services is not a great plan.
