First, I am a Linux admin, so bare with me if I am using the wrong terminology.
We have a Windows 2008R2 server that I routinely have to remote into for some tasks. I use freerdp from a Linux system to remote to the system.
Recently I received an error when trying to remote to the system that said the fingerprint has changed. I had an admin log in and confirm that the thumbprint has indeed changed.
My question is, what would make the thumbprint change? We have had no reinstalls, no cert updates, etc...
