Just upgraded to Win 7 Pro. Have an HP desktop on a wired network. Attached to the router via an ethernet cable, is an Iomega Home Media Network Hard Drive. The software for the NAS creates six network drives that are mapped to my computer. When I open "Computer" they show up under "Computer" in the left hand pane and are listed under "Network Location" as "Network Drives". When I switch to "Network" in the left hand pane the neither the NAS nor the network drives show. What I want to do is to backup my computer to the NAS. Neither the NAS nor the drives show when I try to set up the back up.
