            {

                SPProcessIdentity pi = site.WebApplication.Farm.TimerService.ProcessIdentity;
                string userName = pi.Username;
                object configDB = pi.GetType().GetProperty("ConfigurationDatabase", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(pi, null);
                SPServer server = (SPServer)configDB.GetType().GetProperty("Server").GetValue(configDB, null);
