We all know and love Process.WaitForExit().
Given a pid of a process on a remote machine (created by WMI/psexec), how do I wait for it to end?

Process.GetProcessById(processId, machineName).WaitForExit();
HTH, Kent
For me Process.GetProcessByID() just didn't work (it claimed it couldn't connect to the machine). This worked:
public static bool WaitForProcess(int pid, string machine, TimeSpan timeout)
{
// busy wait
DateTime start = DateTime.Now;
while (IsAlive(pid, machine))
{
if (start.Add(timeout).CompareTo(DateTime.Now) <= 0)
return false;
Thread.Sleep(1000);
}
return true;
}
public static bool IsAlive(int pid, string machine)
{
// doesn't work for me (throws "The network path was not found" exception)
//return Process.GetProcessById(pid, @"\\" + machine) != null;
string user;
string domain;
GetProcessInfoByPID(pid, machine, out user, out domain);
return !string.IsNullOrEmpty(user);
}
public static string GetProcessInfoByPID(int PID, string machine, out string User, out string Domain)
{
