A first look: Inside Windows Home Server (Customer Technology Preview)

Network Health

WHS uses the term "Network Health" to describe the state of backups on your network. If all of your client PCs are backed up and there aren't any patches or updates for WHS, your network will be "healthy."

The same green shield icon is used on each client PC in the taskbar. With it, you are able to see the state of your network as well as log into the WHS console.
