Uninstalling FOG Service on WinXP clients

When running into trouble (re-)installing the FOG Service running on WinXP clients, I have figured out that it helps to remove the entire service:

• click start|run and type: services.msc - stop the FOG service
• open a terminal: click start|run and type cmd
• in the terminal: type sc delete "Fog Service"

The service should now be uninstalled. This means you can reattempt to install the FOG Service.
