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
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".

Information System" under the keyword "Utility", in the section
