Pre-Registration for Sentry EMS and D300M on EMS Cloud


The following guide will allow an EMS Admin to pre-register Sentry EMS and D300M devices for End Users before distributing the devices. At this time, this only applies to EMS cloud accounts. On-Prem EMS support is scheduled for implementation Q2 2018. This guide is only for Sentry EMS and D300M.For other devices please see pg 59 of the EMS Admin Guide. PDF 


A checkbox has been added for the Pre-Registration of a Sentry EMS and a D300M. This checkbox will appear for all devices but will only work with the Sentry EMS and the D300M. If a different device is registered with this checkbox selected then the device will register with the normal workflow and ignore the Pre-Registration checkbox. 


Best Practices:

Upgrade Devices: For full compatibility, DataLocker recommends using this workflow with at least v5.6.0 for D300M devices. All client versions of Sentry EMS are supported with this workflow, however, it is always recommended that devices have the latest device client installed. The latest device client updater for Sentry EMS can be found here: For D300M update please contact Kingston

New Users: This workflow is only suggested for registering new users and new devices.

Disable User Password Reset: Normally, an End User is able to create an online account that will allow them to create a secret question and answer combination. With this information, along with access to the assigned email for the device, the End User will be able to reset their device password at any time. For full control of the devices being deployed, some Admins would like to disable End Users from resetting their own forgotten passwords. While not required for this workflow, this is recommended. To disable End User password resets, create a new EMS policy and follow Option Two of this KB: Sentry EMS - D300M Password Reset .

Mark Devices: D300M devices do not have an external serial number. If multiple devices are going to be registered at the same time, care should be taken not to mix the drives before giving them to the End Users. 




Step 1: Create Activation Code

The System Administrator should generate an activation code by filling out the needed fields, including selecting the default policy to apply to the device and the Pre-Register checkbox. This can be done in the Add User or Add Device section of EMS.

Step 2: Register Device and Update Policy

The System Administrator will plug in and register the device with the activation code. When the Admin is prompted to create a password, they should create a new password that can be shared with the End User. This will be referred to as the Registration Password.

The End User will be prompted to change this password after the first unlock if this workflow is followed correctly.


Upon setup of the device, the System Administrator will need to manually update the device to obtain the correct device policy. This can be done in the UI by going to Settings > Tools > Check for Updates.


If the policy for this device is set to allow End Users to initiate a password reset, the following will happen:

  • An email will be sent to the End User's email address. 

    • The End User will need to follow the instructions in the email before receiving the device (Set up secret question and answer).

  • The Admin will need to remove the device from the computer while the message is displayed.

If these actions do not work for your environment, then User-initiated password reset should be disabled. See above for more information.


If the policy has User-initiated password resets disabled, the device can be locked and removed from the host computer after clicking the Check for Updates button.


Step 3: Give Device to User


The End User will need to finish setting up the device before it can be used completely. This has to be done with a live connection to the EMS server or the device will be blocked. When the End User obtains the device, they will need to enter the Registration Password. If the password is correct, the device will prompt the End User to change the password.


Please note that the Registration Password will not be emailed to the End User. The System Administrator must give the End User the password directly.
