C# run defrag.exe remotely

I am trying to create a utility to defrag all machine on my network. I have had success using WMI's Defrag and DefragAnalysis methods, however they are not compatible with Windows XP. This is a problem as we have some XP machines on the network.
I have been able to locally invoke the defrag.exe process on an XP machine to perform a defrag however I am having problem invoking it on remote machines. Below is my code which works locally, could someone please help me in making this work for remote machines on my network? I have tried using a bit of WMI to help out but as I am new to C# and WMI I haven't had success, thanks!

ProcessStartInfo info = new ProcessStartInfo();
info.FileName = 'defrag';
info.Arguments = volume + ' -f';
info.UseShellExecute = false;
info.CreateNoWindow = true;
info.RedirectStandardOutput = true;

Process defrag = Process.Start(info);
defrag.PriorityClass = ProcessPriorityClass.BelowNormal;

while (!defrag.HasExited)
{
System.Threading.Thread.Sleep(1000);
Process[] procs = Process.GetProcessesByName('dfrgntfs');
if (procs != null && procs.Length > 0)
{
procs[0].PriorityClass = ProcessPriorityClass.Idle;
defrag.WaitForExit();
}

result = null;
while(!defrag.StandardOutput.EndOfStream)
{
//get output and store results
}
