Lights Out

What kind of troubleshooting tools are available? The Network and Sharing Center says in several different ways that the network is out. The red X is kind of obvious, even to me.

 

When you click on the X, Windows will launch a network diagnostic program and attempts to repair or renew the network.

 

The Windows Network Diagnostics checks the hardware and can let you know if the cable is unplugged.
