Maybe you can have a function that checks all valid IP on your LAN Subnet using InetAddress.isReachable..

Get the local machine IP. Use that network portion and try to connect to an open port on the first possible host to the last possible host, add anything that works to a list.That list will then be every active node on the subnet.

You don't need isReachable(). Nobody does really. Just try to connect. If you get an exception on a particular address, forget it.

Hi,

you can use this DOS commande: "net view > c:\all.txt", this commande is listing all network hostes and save the list into the file "c:\all.txt", now all you have to do is to exec this commande and read the result file.

Runtime.getRuntime().exec("net view > c:\all.txt");

//now open and read the file, it contains all hostes.
