After migrating to Active Directory the local machines now do not show the symantec corporate tray icon in the system tray. Even after running the program "vptray.exe" at the startup of the machine it still does not show. The thing is, Symantec Antivirus is running but the icon is just not there. The "vptray.exe" is also running if you look in the processes but still no icon in the tray. If anyone has any knowledge of why please let me know.
