Hm, muss man da etwa programmieren? Ich dachte es gibt eine Einstellung die man machen kann.
Das hier ist genau das was ich meinte:
Zitat:
Legal Notification Dialog Box
In some places, it is legal for anyone who has
access to a workstation to log on and begin working unless there is a notice that indicates that the system is for authorized users only. Also, many users want company-specific messages displayed before normal logon. The standard
GINA uses two Winlogon registry key values to allow a system to display information before logon. If either key value is present and contains a non-null string, then a Legal Notice dialog box is displayed before the usual Welcome screen. These key value names are shown in the following table.
Um etwas Neues zu schaffen muss man seine Ohren vor den Nein-sagern verschliessen um seinen Geist öffnen zu können.
