I'm not expert, but I then the McAfee agent is missing from out ePo server.
If I go to System Tree > Agent Deployment then 2 are listed and both in red saying agent not found. One is called 'My Group' and the other is one I created (and cant remember how) called Mcafee 4.8.1938 agent.
I normally go he to get the manual install file, but the url says 'The agent package for this URL is not valid.'
Makes me think that the auto install of the agent using rogue detection isn't working also.
