Dell Data Protection | Enterprise Edition Shield
How to Determine the Cause:
When accessing log files located in \ProgramData\Dell\Dell Data Protection\Encryption\CMGShield.log(s) you may find the following error:
[06.30.15 09:28:45:426 ExternalAuth: 463 E] [SUPPORT] Authentication - Could not unprotect data [MS error = 0x8009000b]
This error is stating that the User’s password used to seal encryption keys and policy information on the local system did not properly sync with active directory.
This is commonly caused by 3rd party password management software that can update active directory passwords outside of the local computer.
When this password update happens outside of the OS, Dell Encryption Enterprise Shield (formerly Dell Data Protection | Enterprise Edition Shield) may not be able to properly sync the password once it is changed.
With version 8.5.2 and newer, Dell Encryption Enterprise Shield clients have introduced a registry key that allows for detection of this issue and automatic remediation without a reboot.
To Enable Automatic Re-activation, set this key to:
When this triggers, a line in the logs of the client will be generated:
Event Engine - Flagging user XXXXXXX@domain.org for automatic reactivation
A new registry key to record how many times this will have ran has also been generated.
Administrators can monitor how many re-activations have happened per system with this new key.
This will be automatically generated by the shield when a re-activation happens:
WSDeactivate is leveraged to fix this situation. Follow the link below for instructions:
