I have a problem, where my clients are unable to get the task manager to work after pressing ctrl+alt+del, they click on the task manager button at the security dialog and they go back to their desktop without taskmanager running. They can however get the task manager by right clicking on the task bar and selecting it or by using the windows shortcut keys (ctrl+shift+esc). There is no policy for the Task Manager running, The button is still functional, but not displaying the Task Manager. Any advice or help would be nice cheers.
