Mam problem z uruchomieniem pliku z serwera plików przy użyciu Process.Start () + Personifikacja. Pomóż mi rozwiązać mój problem. Czy jest inny sposób, aby to zrobić?

To jest zdarzenie kliknięcia przycisku.

private void btnOpen_Click(object sender, EventArgs e)
    {
        try
        {
            newUser = cls.ImpersonateUser("username", "domain", "password");

            string fileName = @"\\network_computer\Test\Test.doc";

            System.Diagnostics.Process.Start(fileName);
        }
        catch (Exception ex) { throw ex; }
        finally
        {
            if (newUser != null)
                newUser.Undo();
        }
    }

To jest klasa personifikacji.
