Network Magic is a new management program for home networks. It diagrams the network, helps you share files between machines, shows the status of all the components, etc. You load and run this on each workstation on a peer-to-peer network.
There is no support for servers, or Linux, other than identifying the machines on the network.
If you have a peer-to-peer network at home or in a small office, this is a neat program that makes Windows networking tools look clunky by comparison. You can get a free beta version.
