Publishing applications is a feature that comes with Citrix on top
of Windows Terminal Services.
If you don't run Citrix, there are a couple of things you can do
to mimic published applications:
* create a custom desktop for the users on the TS, with only the
shortcuts to the programs that you want them to run. Create a
Group Policy to redirect them to this custom desktop (and possibly
also a custom Start Menu). Use NTFS permissions and/or possibly
AppSec from the Resource Kit to prevent them from running other
applications.
This approach is the easiest to implement and manage
* if you have only a very limited number of applications, you can
create a custom rdp connection for each application and save it on
the users client desktop. Configure each custom rdp connection to
start a different application. Users will never see the Terminal
Server desktop at all. A pain with many users and/or many
applications.
