Experiencing a certificates problem with RDP file which suppose to open a session to one of the Terminal Server and then open a installed application.
We have 10 Terminal Server in the cluster. We have a RDP file located on the user workstations desktop that opens a RDP session to one of the Terminal Server the Cluster and opens a remote app installed on the server.
As of now I got a error message "The digital signature of this RDP File connot be verified. The remote connection cannot be started" after it launches.
I found that a certificate which signs remote apps expired on all servers. I have renewed a certificate and recreated a RDP file. But I unable to start remote connection because of error" The certificate is not from trusted certifying authority (See screenshoot)
Please help to understand what is going on and how to create RDP correctly.
