Kill process on remote machine


I'm trying to kill a process on a remote machine. But I get error. What am I doing wrong and how can I make this work?

My code:

var iu = new ImpersonateUser();
try
{
    iu.Impersonate(Domain, _userName, _pass);

    foreach (var process in Process.GetProcessesByName("notepad", "RemoteMachine"))
    {
        string processPath = pathToExe; //Is set as constant (and is correct)
        process.Kill();
        Thread.Sleep(3000);
        Process.Start(processPath);
    }

}
catch (Exception ex)
{
    lblStatus.Text = ex.ToString();
}
finally
{
    iu.Undo();
}

Just to clarify ImpersonateUser, it makes me login to the remote machine with correct user rights. So the problem is not there. When I debug and check the process object I find the correct process ID for notepad in this case. So the connection works fine. But when I try to kill the process I get this error:

System.NotSupportedException: Feature is not supported for remote machines. at System.Diagnostics.Process.EnsureState


Solution

  • The System.Diagnostics.Process class cannot kill a remote process. You can use the System.Management namespace (be sure to set a reference), to use WMI.

    A simple example is below.

    var processName = "iexplore.exe";
    
    var connectoptions = new ConnectionOptions();
    connectoptions.Username = @"YourDomainName\UserName";
    connectoptions.Password = "User Password";
    
    string ipAddress = "192.168.206.53";
    ManagementScope scope = new ManagementScope(@"\\" + ipAddress + @"\root\cimv2", connectoptions);
    
    // WMI query
    var query = new SelectQuery("select * from Win32_process where name = '" + processName + "'");
    
    using (var searcher = new ManagementObjectSearcher(scope, query))
    {
        foreach (ManagementObject process in searcher.Get()) // this is the fixed line
        {
            process.InvokeMethod("Terminate", null);
        }
    }
    Console.ReadLine();
