Published Application, Parameters are not being applied

I've published an Application with Parameters defined in the "Host Settings" field. E.g. pre-populating the servername.
However it seems the Parameters are not being applied on the session when running the Published Application. When I run the application directly on the RD Session host with parameters, it works.
e.g. Remote Desktop application with servername pre-populated

How can this be troubleshooted please?

 

Hi, if this is specific to the Remote Desktop Client as a published RAS app, you could create a connection on the Remote Desktop client (mstsc) with any settings you require, including computer name, and save the RDP file from the Connection settings and store it somewhere central. From Parallels RAS then publish the mstsc client and add the path of the RDP file in the parameter.
