  1. The recommended way to decrypt the system is through the use of the Decryption Agent (DA). Use of the DA enables the end user to continue using their system while the system is decrypted.
Note: In this example we will be using the 'Download Keys from Server' version of the encryption removal agent uninstall. If you have a previously downloaded key bundle you can use the 'Import Keys from a File' option. Contact support for more information if needed.

Note: Most server information will already be populated. Note that the Device Server URL cannot be changed here, and only the back end server will service forensic key requests. If this URL is pointing to the front end server you will either need to use the 'Import Keys from a File', using the CMGAD.EXE tool to download the bundle, or you will need to edit the Servlet address in the registry. This change could be pushed via GPO or a .reg file manually imported into the local registry. Any account with forensics admin rights can be used.

HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\CMGshield\Servlet(default)=:8443/xapi/

Possible states include:

  • Waiting for Deactivation – DDP|E is still installed, is still configured, or both. Decryption does not start until DDP|E is uninstalled.
  • Initial sweep – The Service is making an initial sweep, calculating the number of encrypted files and bytes. The initial sweep occurs one time.
  • Decryption sweep – The Service is decrypting files and possibly requesting to decrypt locked files.
  • Decrypt on Reboot (partial) – The decryption sweep is complete and some locked files (but not all) are to be decrypted on the next restart.
  • All files could not be decrypted – The decryption sweep is complete, but all files could not be decrypted. This status means one of the following occurred:
    • The locked files could not be scheduled for decryption because they were too big, or an error occurred while making the request to unlock them.
    • An input/output error occurred while decrypting files.
    • The files could not be decrypted by policy.
    • The files are marked as should be encrypted.
    • An error occurred during the decryption sweep.
  • Complete – The decryption sweep is complete. The Service, the executable, the driver, and the driver executable are all scheduled for deletion on the next restart.
