Autoboot fails when the policy is set to use the Trusted Platform Module

Technical Articles ID: KB89061
Last Modified: 2/27/2020

Environment

McAfee Drive Encryption (DE) 7.2.1, 7.2.0

For details of DE supported environments, see KB79422.

Problem

When the Autoboot policy is set to use the Trusted Platform Module (TPM), with the option 'If Available' enabled, the DE Pre-Boot Authentication (PBA) unexpectedly displays, and asks a user to log on.

NOTE: If the TPM policy is set to Never, Autoboot functions as expected.

The MfeEep.log records the following error:

INFO SystemAutoboot Autoboot successfully enabled using TPM.

Cause

On the target system, the hardware does not support TPM.

Solution

This issue is resolved in DE 7.2.2 (build 7.2.2.14), which is available on the Product Downloads site.

To review other DE known and resolved issues, see KB84502.

Our product software, upgrades, maintenance releases, and documentation are available on the Product Downloads site.

NOTE: You need a valid Grant Number for access. See KB56057 - How to download Enterprise product updates and documentation for more information about the Product Downloads site, and alternate locations for some products.

NOTE: This issue was previously resolved in DE 7.2.1 Hotfix 1199587 (build 7.2.1.19), which was only Released to Technical Support (RTS). This hotfix is no longer available.

Workaround

Set the Autoboot policy to Never when using TPM, unless the system supports TPM.
