We've deployed EMET on about 40% of our in-house PCs and a vast majority, although having at first, no longer have the EMET Agent tray icon showing up in the Notification Area/System Tray. Because of this, users are not alerted when a mitigation has taken place, and an event is not logged to the event log. To note, EMET_Agent.exe has started and the GPO for Reporting to Event Log, Tray Icon and even Early Warning are enabled.
Any idea why the tray icon wouldn't be showing up?
Whoops... always useful to make sure that the "EMET Agent Visibility" policy is set to disabled if you want the EMET Agent visible.
