Before uninstalling the Security Client on a machine, you should do the following:
On the machine, move any files from encrypted safe harbor locations to unencrypted locations. This decrypts the files and ensures that they will be available after the client is uninstalled. In addition, you should export the encryption keys in case any orphaned encrypted files remain; the encryption keys can then be used with the decryption utility to decrypt the files. For help exporting the encryption keys, see Section 7.1, Exporting Encryption Keys. For help using the decryption utility, see Section 24.0, ZENworks File Decryption Utility.
Distribute a simple policy to the machine. Have the policy disable encryption and enable communication hardware and storage devices.
Eject the wireless card prior to uninstallation, switch off the Wi-Fi radio, and close all software with a network connection (for example, VPN or FTP software).
