Novell ZENworks 10 Configuration Management Installation - Agent
The logged in Ctrl-Alt-Delete functionality no longer works correctly after un-installing agent. Once the ZCM agent is uninstalled, pressing Ctrl-Alt-Del shows nothing. It doesn't show the Windows Task Manager or the appropriate GUI. The result is a blank screen without any GUI control which to take action with. The only option is to hard reset the system with the power button.
This is fixed in version 10.1 - see KB 7001200 "ZENworks 10 Configuration Management with SP1 (10.1)" which can be found at https://www.novell.com/support
