We have the same issue as above.
We have an epolicy 4.6.0 (build 1029) server. All extentions are checked-in.
Client version is 8.8 with patch 2 and 3 available on epolicy.
Agent version 4.6.0 (3122).
We have one new server which is installed with Server 2012. The agent on this server communicates with epolicy and is receiving policy updates. However, it is NOT receiving any tasks from the server.
I manually updated the agent version on this server to 4.8.0 (887) and checked-in this package on the epolicy server. Still, have no luck sending tasks to this server. Creating tasks manually on this server works as expected.
Only indication that something might be wrong is the behaviour explained in this KB:
There are no errors in the event viewer, mcafee logs or anything. Just tasks are not showing up on the 2012 server.
If anybody has some good ideas, please. I'm running out of options.
