When the Hardware Crypto Accelerator has used all of its lifecycles, the Shield erroneously asks the user for their Hardware
Crypto Accelerator Password and Preboot Password. The message should notify the user that the computer does not have
any remaining lifecycles and to contact their Administrator to get a replacement Hardware Crypto Accelerator. We expect
this scenario to rarely occur. [22492]
Amended 01/2014 - When using VMware, if the host computer is Shielded (essentially meaning that the port control
drivers are installed on the host), when a user connects a USB device to their computer, and forces it to connect
to the OS running on the VMware computer instead of the host OS, the VMware OS will not be able to access the
files on the USB. The Dell port control driver is a filter driver running on USB stack. VMware is not compatible with
USB filter drivers. For more information, see VMware KB article: http://kb.vmware.com/selfservice/microsites/search.do?
language=en_US&cmd=displayKC&externalId=1016809. [20280, 22820, 28522]
When using Windows Vista (x86 or x64), the Shield failed to load the user's profile. To workaround this issue, reboot the
computer. [23496]
The Encryption Removal Agent can decrypt files with path lengths up to 256 characters. Files paths longer than 256
characters result in a decryption failure. To work around this issue, shorten the path length to less than 256 characters and
re-initiate the Encryption Removal Agent. [23474, 23510]

Encryption
When scanning very large files on removable media, there is a slight screen refresh delay between the local console and the
External Media Edition dialog that displays the files name that are being processed. No loss of functionality is experienced.
[23453]
When ejecting removable storage without clicking the "safely removing devices" option in the system tray, the local console
status line briefly flashes the "Not Attached to the Encryption System" message. The status resolves to the correct status
within a second or two. This is slight screen refresh delay between the local console and External Media Edition. No loss of
functionality is experienced. [23454]
Repeatedly switching between multiple users and using fast user switching will eventually result in Dell Data Protection |
Encryption becoming unmanaged. To identify if you are experiencing this issue, you will get a message from the local console
stating the "Connecting to Dell Data Protection | Encryption..." message, however, the connection will never be made. A
computer restart corrects the issue. [23448]
System Restore is not a full backup/restore utility. Only the following are restored when using System Restore:
Registry
Profiles
COM+ DB
WFP.dll cache
WMI DB
IIS Metabase
File types which are monitored by System Restore are as specified in http://msdn.microsoft.com/library/en-us/sr/sr/
monitored_file_extensions.asp. Using System Restore on any of these files which are encrypted by Dell Data Protection |
Encryption can potentially cause corruption. Backup and restoration of Shield-encrypted files should be done at the folder
level and not on an individual file basis. [23437]
