After I updated server and agents with 10.1.1 update, remote control started to act funny. When I try to connect to some workstations, I get message "Waiting for user to accept connection..." and stays like that. Before the update all worked fine. After rebooting same machine, I can remote control it, but just for a few seconds, and then connection brakes. Next time when I try to remote control, same message appears. What to do?

Thanks in advance!
