Hi Neil It depends how you use the threads ...
You would need to have a controlling thread of some sort that would collate the ping results from the ICMP threads and return the list of results to your app. You should also check that the threads are being assigned different IPs to ping. i.e. if two threads are trying to ping the same pc at the same time, one will return true and the other false; and since the false thread will have ping timeout it will return last and cause the computer to appear to be off. For the ones that return true, it might be that IP address that it returned is not the ip that it actually pinged?? not sure about this though?
