Wait for a remote process to finish in .net

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?

From stackoverflow

• Process.GetProcessById(processId, machineName).WaitForExit();

• Poll the remote computer using SysInternals' PSLIST.

• 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)
  {

    // with slight modifications
    ConnectionOptions connOptions = new ConnectionOptions();
    connOptions.Impersonation = ImpersonationLevel.Impersonate;
    connOptions.EnablePrivileges = true;
    ManagementScope manScope = new ManagementScope(String.Format(@"\\{0}\ROOT\CIMV2", machine), connOptions);
    manScope.Connect();
  
    User = String.Empty;
    Domain = String.Empty;
    string OwnerSID = String.Empty;
    string processname = String.Empty;
    try
    {
      ObjectQuery sq = new ObjectQuery
        ("Select * from Win32_Process Where ProcessID = '" + PID + "'");
      ManagementObjectSearcher searcher = new ManagementObjectSearcher(manScope, sq);
      if (searcher.Get().Count == 0)
        return OwnerSID;
      foreach (ManagementObject oReturn in searcher.Get())
      {
        string[] o = new String[2];
        //Invoke the method and populate the o var with the user name and domain
        oReturn.InvokeMethod("GetOwner", o);
  
        //int pid = (int)oReturn["ProcessID"];
        processname = (string)oReturn["Name"];
        //dr[2] = oReturn["Description"];
        User = o[0];
        if (User == null)
          User = String.Empty;
        Domain = o[1];
        if (Domain == null)
          Domain = String.Empty;
        string[] sid = new String[1];
        oReturn.InvokeMethod("GetOwnerSid", sid);
        OwnerSID = sid[0];
        return OwnerSID;
      }
    }
    catch
    {
      return OwnerSID;
    }
    return OwnerSID;
  }
