Yes, FIMS can be accessed through a terminal server.  However, there is some setup required.

We will need to install the Progress OpenEdge software on your terminal server, and adjust the FIMS configuration files so that when launching FIMS from the terminal server, it uses the local instance of Progress, but reaches to your Database server for the database. 

If you or your IT are looking to setup a terminal server, it's best to contact us to arrange the Progress OpenEdge Installation and configuration.  Please keep in mind that when using a terminal server, you are subject to a new set of potential network issues and problems - that is not something FIMS Support is capable of assisting with, and is the responsibility of your IT.
