The 'Lock Screen' tab in Impero Server allows you to modify the screen that displays to users when their screen has been locked by Impero. If you wish to change the background image that appears when a screen is locked, tick the option to 'Use Custom Lock Screen image'.
The 'Browse' button then becomes active, allowing you to navigate through your file system to the image that you wish to make your lock screen background. Please ensure your custom image is local to the Impero Server machine. Once you have selected your image, it will load into the 'Preview' panel on the right-hand side of the window.
You can modify the color of the text that is displayed on the lock screen by clicking in the colored squared in the center of the screen. This opens a new window in which you can select from a list of basic colors or define your own custom color. Click on 'OK' to make your selection; the 'Preview' window then changes to display the 'AaBbCc' text in your chosen color.
The final two options in this window allow you to modify the text that will appear when a user screen is locked:
The text when an Impero Policy locks the Screen
This is the text that is displayed on the user screen if a screen is locked either manually by an Impero Console user or automatically via an Impero Advanced Policy.
The text when the network cable is pulled out
This is the text that is displayed on the user screen if a user removes the network cable from their computer, and the option to lock screen if a network cable is pulled out is enabled.
Once you have configured your lock screen options, click on 'Apply' to set your changes.
Note: Once you press 'Apply', your lock screen image is automatically copied to your Impero Server directory (usually C:\Program Files (x86)\Impero Solutions Ltd\Impero Server\Data\image.jpg). The location displayed in the 'Lock Screen' tab will change to point to the copied image, rather than the image in your originally selected location.
