Marantz PMD 580 Help


I have just got two of these (Marantz PMD 580's) for my Church and have set them up to record sermons, I can access the web based interface to control the unit and alter settings, but for the life of me I can't get the auto archive feature to work via the network to our PC running windows 10.
Does anyone have any experience with this unit and can you help me with the settings I need to use.
Thanks
