However, there shouldn't be any messages like "Current session on hold". Are you sure you are using Remote Utilities' own Full Control mode, and not the RDP mode?
Well that's sort of the problem, I don't get messages it's paused. Therefor I was looking all the time why my session had stopped suddenly. It didn't respond and gave no messages why. After a few month searching within your forum, faq and RU-client I found it was "put the current session on hold". First I thought it was a connection problem or some program freeze... And therefor I was restarting my client all the time.
I'll try again to explain... The problem I have with Remote Utilities Server is that it disconnects sometimes, because of a network hiccup or due to a switch/router restart. When this happens the RU-server doesn't reconnect automatically. Because all hosts are configured with a specific network address (domain.tld), you aren't able anymore to connect by using your own Internet-ID.
To prevent this issue, I am looking for a simple task to check and if disconnected reconnect RU-server.
