Discover Can't find drive

I run a windows 7 system on a domain and can’t find the My Book Live Duo using the Cd that came with the drive. What would the default ip address be for the drive? 

There is no default.   You need to have DHCP enabled on the subnet, and if necessary, check the DHCP server logs to see what address it assigned.

If I scanned the subnet what would the Hostname be?

I found it. Thanks for your help you bunped me in the right direction.

Curiousity here - what did you do to fix this issue? Our CD relies on uPnP to discover our devices on the network. If by chance you have an older router or the router has defaulted uPnP to off, this might be why. Let me know your details.
