I searched the .Net BCL for a solution to this, and then I had to go back to net.exe to do this. This is a very brittle solution, so if you have a better one, dont forget to enlighten me.

{
_machineIPs.Add(IPAddresses(machine));
}
return _machineIPs;
}

{
string _allMachines = processOutput.Substring( processOutput.IndexOf("\\"));
