We have install McAfee Agent 4.5 patch 3, VSE 8.7i patch 3, DLP Agent 9.0 patch 1 on our company, Almost all client use Windows XP SP3, Some use Windows Vista SP2. All windows xp Client McAfee Agent 4.5 is show icon on the system tray. Some of Vista have problem to show McAfee Agent icon. The odd thing is when user use have local admin account access PC didn't show icon, if use other no local admin account access PC do show icon. All client have DCon it, so where should I check with it?
