I recently upgraded from eset 5 to 6.5 and I am having trouble activating all my clients. Most of they will activate, but I currently have 48 computers that will not activate through the ERA activation task. I am able to contact these machines, I can even send commands to them (reboot, policy change), but the activation comes back as failed for them. The rest of my machines are working fine. Any ideas?
The machines range in vender and OS. from windows 7 to windows 10. I have HP, Dell, and lenovo machines. The ones that activate and the ones that don't activate are found in all the range. I can't seem to find a common issue that all the ones that will not activate share.
