Details
The PSD is disabled and cannot be
deleted after formatting the secondary
hard drive on which the PSD was
generated. The PSD icon is still visible,
but the error message drive is not
accessible appears when the user
attempts to access the PSD.
User is not able to delete the PSD and a
message appears that states: your PSD
is still in use, please ensure that your
PSD contains no open files and is not
accessed by another process. User
must reboot the system in order to delete
the PSD and it is not loaded after reboot.
If the user
● clicks Restore under Backup
option of Embedded Security in
HPPTSM to restore from the
automatic backup Archive
●
selects SPSystemBackup .xml
the Restore Wizard fails and the
following error message is displayed:
The selected Backup Archive does
not match the restore reason. Please
select another archive and continue.
During the restore process, if the
administrator selects users to restore,
the users not selected are not able to
restore the keys when trying to restore at
a later time. A decryption process
failed error message is displayed.
Resetting the system ROM to default
hides the TPM to Windows. This does
not allow the security software to operate
properly and makes TPM-encrypted data
inaccessible.
When an administrator sets up
Automatic Backup in Embedded
Security, it creates an entry in
Windows > Tasks > Scheduled Task.
This Windows Scheduled Task is set to
use NT AUTHORITY\SYSTEM for rights
to execute the backup. This works
properly to any local drive.
When the administrator instead
configures the Automatic Backup to save
to a mapped drive, the process fails
because the NT AUTHORITY\SYSTEM
does not have the rights to use the
mapped drive.
If the Automatic Backup is scheduled to
occur upon login, Embedded Security
TNA Icon displays the following
message: The Backup Archive
location is currently not accessible.
Solution
As designed: If a customer force-deletes or disconnects
from the storage location of the PSD data, the
Embedded Security PSD drive emulation continues to
function and will produce errors based on lack of
communication with the missing data.
Resolution: After the next reboot, the emulations fail to
load and user can delete the old PSD emulation and
create a new PSD.
If the user selects SpSystemBackup.xml when the
SpBackupArchive.xml is required, Embedded Security
Wizard fails with: An internal Embedded Security
error has been detected.
User must select the correct .xml file to match the
required reason.
The processes are working as designed and function
properly; however, the internal Embedded Security
error message is not clear and should state a more
appropriate message. HP is working to enhance this in
future products.
The non-selected users can be restored by resetting
the TPM, running the restore process, and selecting all
users before the next default daily back runs. If the
automated backup runs, it overwrites the non-restored
users and their data is lost. If a new system backup is
stored, the previous non-selected users cannot be
restored.
Also, user must restore the entire system backup. An
Archive Backup can be restored individually.
Unhide the TPM in BIOS:
Open the Computer Setup (F10) Utility, navigate to
Security > Device security, modify the field from
Hidden to Available.
The workaround is to change the NT AUTHORITY
\SYSTEM to (computer name)\(admin name). This is
the default setting if the Scheduled Task is created
manually.
HP is working to provide future product releases with
default settings that include computer name\admin
name.
