Sorry for my very late reply. I didn't check this post anymore!
I appreciate the replies, thanks for that! However, I'm not able to connect the source computer to a different network and connect it back to the original network. They don't have Wi-Fi, and their LAN is connected to a secured network.
From the log file "remotecontrolagent.log" (on the source computer), I can see the following:
(This is exactly the issue that you described, but since I cannot connect the computers to another network and back, what else can I do?)
