These tools are designed to run from a USB flash drive.
You need a flash drive with the capacity of at least 1 GB to run the tools. For restoring the default configuration, 256 MB
suffice.
We recommend using these tools for Kerio Control Box and Kerio Control Software Appliance. In this article, Kerio Control
refers to Kerio Control Box or Kerio Control Software Appliance.
NOTE
This article describes Kerio Control Box 1000/3000 series.
For more information, refer to
Restoring the Kerio
Control Box NG series default configuration using a USB flash drive
(page 372).
Should any issues arise (for example, if Kerio Control fails to work even after you perform a complete system recovery)

Restoring the default configuration
The factory settings of Kerio Control can be recovered with the file
kerio-control-factory-reset
.
Factory settings recovery includes removal of all configuration data including activation and the statistics database.
This USB 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.
1.
Insert a USB flash drive to your computer (256 MB or larger) into a USB port on your computer.
2.
Make sure that only one partition with file system FAT16 or FAT32 (VFAT ) is created on the flash drive. The USB drive
must not be formatted by file system NTFS or ext2, ext3, or ext4.
3.
Save the
kerio-control-factory-reset
file to the flash drive.
4.
Switch off Kerio Control.
5.
Plug the USB flash drive into one of the USB ports of your Kerio Control.
6.
Switch on Kerio Control. Once Kerio Control boots, the box beeps once. Once the configuration is reset, the box
beeps once.
7.
Kerio Control re-boots automatically and beeps once. Once Kerio Control is up, the box beeps three times.
8.
Install Kerio Control.
For more information, refer to
Installing Kerio Control
(page 22).
If the steps above do not work, try another flash drive. Different Kerio Control Box models require different USB drive
formats:
Kerio Control Box 1110, 3110, 3120, and 3130 require a USB flash drive formatted like a floppy disk (not partitioned).
Kerio Control Box 1120 requires a flash drive formatted with a master boot record (MBR). USB drives with floppy-type
formatting cannot connect to Kerio Control Box, but can be reconfigured to work.
For more information, refer to
For-
matting a USB flash drive with MBR
(page 378).
Running a complete system recovery
Kerio Control can be completely recovered with the
kerio-control-rescue
file. In the system recovery, all configuration
data, including activation and the statistics database, is completely rewritten. This means the device have to be
reactivated and reconfigured for further use.
