What error are you getting?

Do it this way:

protected void Login_Authenticate(object sender, AuthenticateEventArgs e)
        {
            Boolean blnresult = Authentication("userName", "password"); //provide 2 arguments in here!!!!
            if (blnresult == true)
            {
                e.Authenticated = true;
                Session["Check"] = true;
            }
            else

                e.Authenticated = false;
        }

        protected static Boolean Authentication(string Username, string Password)
        {
            string sqlstring;
            sqlstring = "SELECT userID FROM import_log.dbo.user_verification WHERE userID =" + Username + "";

            System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection("Data Source = ietm-fwb-sql1; Initial Catalog = import_log; Persist Security Info = True; User ID = sa; Password = fwbadmin");

            System.Data.SqlClient.SqlCommand comm = new System.Data.SqlClient.SqlCommand(sqlstring, con);

            System.Data.SqlClient.SqlDataReader reader;

            con.Open();

            reader = comm.ExecuteReader();

            if (reader.Read())
                return true;
            else
                return false;
        }
    }

I'm getting the error that an object reference for the non-static field, method, or property "System.Web.UI.WebControls.Login.UserName.get"

Mitja, I am still getting an error (the one that is posted below)

Do it this way:

            {
                e.Authenticated = true;
                Session["Check"] = true;
            }
            else

                e.Authenticated = false;
        }

        protected static Boolean Authentication(string Username, string Password)
        {
            string sqlstring;
