I have updated to 8.5.3 on both machines and emailed the log files. The connection is still dropping.
Reproducing the problem is simply connecting to the machine. Before the update, I would connect then have Desktop control for a few moments and then the screen would freeze and the connection would drop showing the error “Connection reset by peer”. Since the update, I connect but I don’t even have Desktop control for a few moments. It freezes automatically and drops the connection with the same error.
