Connection to the SIMATIC WinCC flexible Sm@rtServer gets lost (with active screensaver or "Shut Down")
As soon as I lock my workstation (PC) with "SIMATIC WinCC flexible Sm@rtServer" running (e.g. via Ctrl+Alt+Del and "Lock Computer"), or the screensaver becomes active, my Sm@rtClients lose their connection to the Sm@rtServer. What settings do I have to make to avoid this?
If the Sm@rtServer is not running as a utility on the server operator panel, then the connection set up with the Sm@rtClient application is interrupted automatically as soon as you press the key combination Ctrl+Alt+Del on the server control panel or the screensaver becomes active. Proceed as follows to avoid this:
- Start the Windows Control Panel.
- To have the Sm@rtServer run as a utility you must got to "Internet Settings", select the "Remote" tab and enable the check box "Start automatically after booting".

- Then reboot the computer.
