Continuous Running Problems
SOLUTION: AKA from NetShift Software Ltd.
Many kiosks are expected to run continuously without problems in a 24/7 manner. To get this level of service in mission critical situations requires a battery of servers, UPSes, controlled environment in secure rooms etc. A kiosk probably has none of these and maybe is even running Windows 95 which isn't even a Server Operating System.
A recent warning from Microsoft attached below points out one potential cause of problems, however NetShift Software Ltd has been aware of these types of problems for a long time and has released a Free utility for its software users.
This utility is the NetShift AKA (Automated Kiosk Attendant).
WHAT IS AKA v2.0?
AKA is a free a kiosk software utility developed as a companion product to the NetShift Public Browser Interface (PBI) software. Whilst NetShift is a kiosk client front end product, AKA is designed as a kiosk client back end product to optimise both Windows 95 and NT for 24/7 operation.
(AUTOMATED KIOSK ATTENDANT UTILITY)
Some of its many features and benefits are:
PASSWORD ENTRY INTO SHELL MANAGER
As kiosk boots up.. X seconds (customisable) are allowed for the password entry box (to the AKA Setup manager) to be on view. As a second security option Y seconds of attempts (customisable) for password text entry time.
CONTROLLED LAUNCH OF EACH STARTUP APPLICATION
As an alternative to the 'rough and ready' launch of applications from the Windows start up folder is the ability to select the EXE's to be run and allow X seconds between the launch of each EXE. This provides for a much smoother and trouble free launch of programs that may hog system resources during their launch.
DETECT EXE FAILURE AND THEN REBOOT KIOSK
AKA continually looks for EXE failure after X seconds and will automatically reboot the system for a fresh restart.
AUTOMATIC KIOSK REBOOT SCHEDULAR
Imperative for 24/7 optimization, the system must be regularly shut down and restarted to clear cache, free up resources etc This option is provided for within the AKA Setup Manager to Automatically restart the kiosk X interval/s per day at Y Hour/s time.
OPTION - TYPE OF REBOOT
There are a selection of reboot options available in the AKA setup manager to suit your particular system operation.
OPTION - SET SHELL AS..
Main option choice would be set set shell as 'AKA Shell' so that in the event of system failure or when system is rebooting the standard windows desk top (including launch icons) is not seen, but instead a safe plain blank desk top. Or you could add a message as a full screen wallpaper instead of showing a blank desk top - for further details please send a blank e-mail to email@example.com with the words 'Windows Startup & Shutdown screens'.
OPTION - RUN SCAN DISK IN AUTO MODE
To further optimise the kiosk system for 24/7 operation, to run scan disc at each system reboot.
OPTION - BYPASS WINDOWS LOG IN
Required option within AKA Setup manager to bypass the Network log-in dialogue box. For this to work when running Win 95 you will need to have on your system Power Toys/TweakUI, this is free from Microsoft website (not needed for NT operation).
AUTO RESTORE MINIMISED APPLICATIONS
Normally, for security reasons when running NetShift, Windows has no task bar. If another application is run from NetShift and that application has a minimise button and minimise is selected... then the minimised application will drop off the bottom of the screen making recovery impossible and halting the user operation at this point. Auto restore looks for minimised applications and auto restores them - hey presto!
OPTION - GENERATE AN AKA LOG FILE
Option - Generate an AKA log file, useful internal log file to check to see daily run routine of AKA - has various sub options
OPTION - SYSTEMS RESOURCE VIEWER
Windows Explorer/Look up style facility from within the AKA to the rest of your system without the requirement to shut AKA down
OPTION - CUSTOMISABLE MESSAGES IF TOTAL SYSTEM FAILS
If AKA detects TOTAL failure of an EXE's to launch then to prevent the AKA going into a continuous reboot loop it will halt the kiosk and display a configurable message to the user that the system has failed. The customisable message, example: 'maintenance phone number or contact details' can be displayed on the screen.
OPTION - HEARTBEAT
The ability to switch on a heartbeat from AKA that could be recognised by third party hardware reboot watchdog. This would enable the hardware watchdog to detect a total windows system freeze as no pulse is being detected from the AKA heartbeat.
OPTION - KEYBLOCKING
Brings in the NetShift style external keyboard blocking early (as NetShift is run after AKA)
Plus other industry standard options as would be expected from a high quality software OEM: 'save configuration' 'Uninstall' etc
The AKA (PBI version) only works with NetShift v4.2 and later versions.
