Yes reboot will fix it. If you are ePO admin then select all your machine under system tree with a single check box at the upper bar and then at the bottom click Wake agent. Could you wakeup McAfee agents on clients in this way or if you already have don it then Reboot is required.
Just tried another workstation doing an agent wake-up call.
I checked off force policy update (force complete policy and task update)
I also change the number of attempts to 2 to make sure. It is now over 15 minutes
later and the system is still showing the last CLP to ePO communication was on 20
June. The McAfee agent has communicated today without issue.
Thank you again,
can you browse that machine from ePo
http:// machine ip:8081 or can you see agent logs under system tree>Action>Agent>Show agent log? can you confirm the ASCI from this log?
can you telnet this macine on these ports
8081 80 and 443
