5.4.8 Diagnostic tool for Kerio Control Box NG series Kerio Technologies provides a tool for diagnosing hardware problems with the Kerio Control Box NG series. This tool
collects crucial information for the Kerio Technologies technical support. It is designed to be run from a USB flash drive.
You need a USB flash drive with a capacity of at least 256 MB.
The diagnostic tool is designed for a single use. An operation does not repeat if you restart with the flash drive still in the
USB port. Once you perform the operation unplug the flash drive.

kerio-control-usbdiag
, is an image of an installation disk and must be saved directly on the
physical device. Follow the instructions for your client system below.
