Overview

The Kerio Control may return "session expired" error when attempting to login into Kerio Control Administration panel. In such cases, password recovery using a USB flash drive procedure can be applied. This procedure can be used by administrators whenever an access password to a device is lost.

The password recovery tool is designed for a single-use. Once you execute this procedure, the content cannot be reused even if you restart with the flash drive still in the USB port.

Prerequisites

For this procedure, you need:

• A USB flash drive. Keep in mind that different Kerio Control Box models require different USB drive formats:

  • Kerio Control Box 3110, 3120, and 3130 need 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).

• Browser to access Kerio Control's administration interface afterward.

Note: This article applies to the Kerio Control Box 1000/3000 series only. For Kerio Control NG series, refer to  Recovering Kerio Control Box NG Series Password Using a USB Flash Drive.

Solution

IMPORTANT: Kerio Control Support recommends this method to reset the password for the Kerio Control Box and Kerio Control Software Appliance (SA). In this article, Kerio Control refers to both Kerio Control Box or Kerio Control SA.

1. Insert a USB flash drive into a USB port on your computer.

   Note: Make sure that only one partition with the FAT16 or FAT32 (VFAT) file system is created on the flash drive. The USB disk must not be formatted by the NTFS, ext2, ext3, or ext4 file systems.

2. Download and save the kerio-control-password-reset file into the flash drive.
   

3. Turn off Kerio Control.

4. Plug the USB flash drive into the USB port of your Kerio Control Box or the computer where the Kerio Control Software Appliance is installed.

5. Turn on Kerio Control. The password will be automatically reset, and the box beeps once.

6. Wait for the Kerio Control Engine to start up (after three beeps).

7. In your web browser, open the Kerio Control's administration interface. The activation wizard opens.

8. The wizard asks for a new administration password. Create a new password for the admin account and follow the instructions until completion.

Confirmation

Open Kerio Control's administration interface and log in using the new password; you are now able to access the administration interface.
