74 Enterprise Edition Administrator Guide
• Optionally create an Encryption Removal Agent log file to aid in troubleshooting. See How to Create an Encryption
Removal Agent Log File (Optional). If you do not intend to decrypt SDE, User, or Common encrypted files during the
uninstall process, you do not need to create an Encryption Removal Agent log file.
• You must have a
local or domain Admin user
account to perform the uninstallation.
• Dell ControlVault is typically not uninstalled, as it is a driver for your fingerprint reader.
Uninstall Encryption Client
Before you begin, ensure the following items are complete:
• If the uninstallation target device is activated against a DDP Enterprise Server, ensure that a domain account is
configured for the “Logon As” in the Dell Key Server service.
• If the uninstallation target device is activated against a DDP Enterprise Se
rver, ensure that the DA_RUNAS user is in the
Key Server list in the Remote Management Console.
• See How to Create an Encryption Removal Agent Log File (Optional) for instructions on how to create an Encryption
Removal Agent log file.
• See Check Encryption Removal Agent Status for information on how to check decryption status following uninstallation.
NOTE: If performing a silent uninstall of a client that is activated against a DDP Enterprise Server - VE and using a password on the command
line is a security concern, Dell recommends that the administrator:
1. Create a Forensic Administrator account in the VE Remote Managemen
t Console for the purpose of performing the silent
uninstallation.
2. Use a temporary password for that account that is
unique to that account and time period.
3. After the silent uninstallation has been completed, remove the temporary account from the list of administrators or change its
password.
Command Line Uninstallation
For a command line uninstallation, the switches must be specified first. The /v switch is required and takes an argument.
Other parameters go inside an argument that is passed to the /v switch.
