Technical Advisories v1.7.1
Encryption Client v8.17.1
● In some cases, a device may not show in compliance after sweep completes. The current workaround is to reboot the device.
[DDPC-7977]
Preboot Authentication v8.17.1
● In some cases, the intensity of USB Type C mouse seems to strengthen while user is in PBA on a UEFI machine.
[DDPC-7885]
● When a network cable is unplugged after loading the PBA, there is no IP address captured which causes the server sync to
fail. [DDPC-7936]
● Added 05/2018- In some cases, the touchpad becomes unresponsive during the PBA login screen on a M300 machine with
Windows 10 installed in UEFI mode and PBA enabled. [DDPC-8206]
SED Management v8.17.1
● The Oberthur chip only smart card ID-One COSMO V7.0 is read by the PBA but fails to log in on a UEFI machine.
[DDPC-7985]
Full Disk Encryption v1.1
● When the network cable is disconnected during PBA recovery and then connected after FDE has been activated, the PBA
screen on a UEFI machine displays "Loading data please wait" and freezes. [DDPC-8014]
Legacy Boot Mode FDE
For beta testing in non-production environments
● Currently, a message of " Missing OS" appears after FDE has been activated and machine has been rebooted. [DDPC-7806]
● In some cases, SSO to Windows issues appear in Legacy FDE. [DDPC-7926]
Bitlocker Manager v8.17.1
● The policy line of: <PasswordUse MinimumPasswordLength="8" PasswordComplexity="Allow" Usage="Allow" />
is forcing a secondary drive, which the D: drive is being seen at, to unlock with a password. Before the password unlock, this
volume is not mount-able. It seems that once this is unlocked, the shield is not properly seeing this drive being mounted as a
"Fixed disk", even though PCS is classifying it as:
[01.15.18 15:03:37:219 PCSInfoLogger: 53 D] [PCSQuery] Retrieved drive information from PCS driver. DeviceType: 0, Device
Class: 0, Device ID: SCSI\Disk&Ven_HFS512G3&Prod_9MND-3520A\4&9e95efc&0&000200
The workaround is to change the BitLocker Policy under the Fixed Disks to: Configure Use of Passwords for Fixed Data
Drives and setting this to "Disallow". The disk will use the TPM settings for the OS disk to provision a protector instead of
the password that is user-defined. [DDPC-8002]
New Features and Functionality v1.7
● Added 01/2018- Dell's Preboot Authentication environment for Self-Encrypting Drive and Full Disk Encryption now has
built-in resiliency. If the data-store for user credentials in the PBA becomes corrupted, it will revert to a known-good
database. This can be manually initiated by holding the Control and Alt keys, and then pressing 'b' on the keyboard.
