+1  A: 

You could try sending out a ping message but it's unlikely that all nodes will reply to it.

The most reliable way to detect nodes is to perform ARP requests. You'll need to control a node inside the LAN (ARP requests don't pass through routers).

in .net 3.5 there is ping utility class which is also faster way to discover nodes in .net
