You cannot change encryption policies.
EEPC will stop getting policy or user updates from ePO. Once you push the new agent installation from ePO and it is installed and started then EEPC will start communicating with ePO again.
If the machine ID changes as a result of re-adding the system to ePO or any other operation then the EEPC will detect this and backup the keys again.
The same applies when migrating an EEPC client from one ePO server to another.
Ok thanks. Does that mean then that I have to use the EETECH tools on that machine to remove the encryption and add it again before i can manage it properly again?
Is there any other way of resolving communication with this machine?
No you should not need to touch EEPC at all.
EEPC will function without a problem withou being able to communicate with the server and will remain with the same settings enforced as the last time it communicated with the server.
Once you reininstall the McAfee Agent EEPC will detect it and communicate with the server.
One reboot or service (McAfee EndPoint Encryption Agent Service) restart maybe required after the new agent is installed.
I would just like to thank you for the answers.
Also password synchronization will stop working.
