Thanks, Pauline! I followed your instructions on the laptop that I am using on my Indiana trip and was able to completely resolve the problem. I also appreciated the included explanation and description. It helped to fully understand the factors that contributed to the problem.
I have noticed something that sounds like this problem. My office is in California, but I am currently in Indiana helping a client get a new server installed. I use Remote Utilities to keep connected to all clients from my office in California and via my laptop when traveling.
I am using Remote Utilities PRO v184.108.40.206 and on my office system (in California) I can load the Viewer, but there is NO LIST of systems... and on my laptop (in Indiana), I get a 'EReadError' or 'Stream Read Error' and NOTHING shows and the Viewing Form does not fully render itself.
