Hi. I tried to upload McAfee VirusScan Enterpris 8.5.0i onto a Unity 4.2 server and it failed. The service 'AvDSDomino' service hung in 'STARTING' status and wouldn't give a stop/start option or start until AV was removed. At this point the message store came back on-line. Anyone come across this or any ideas? Cheers, Niall
