Indigo for Windows has the ability to install itself as a system service, which enables your computer to run a Network Slave during screensaver. This is useful for utilising idle office workstations to accelerate network renders.
To enable the Windows service, navigate to your Indigo installation directory and run the "network_client_service_manager.exe" application, and click the "Install Service" button.
Uninstalling the service can also be done from this dialog, by clicking the "Uninstall Service" button.
Once the service is installed, when the computer goes into screensaver mode, it will start an Indigo Slave and contribute to any active network renders. When the computer exits the screensaver, the rendering is halted to free up the computer for use.
