As a computer field tech, I use the remote desktop program UltraVNC quite often. I utilize it mostly to connect to offsite computers so I can run diagnostics and repair remotely, if needed.
Recently, I ran into an issue with UltraVNC and Vista. I was able to connect but the desktop was slow to the point of being almost non-responsive. There was no way I would be able to diagnose let alone repair anything over that connection.
