private void button1_Click(object sender, EventArgs e)
    {


        var url = "servicsURL";

        try
        {
            var myRequest = (HttpWebRequest)WebRequest.Create(url);
            NetworkCredential networkCredential = new NetworkCredential("UserName", "password","domain");
            // Associate the 'NetworkCredential' object with the 'WebRequest' object.
            myRequest.Credentials = networkCredential;
            var response = (HttpWebResponse)myRequest.GetResponse();
            if (response.StatusCode == HttpStatusCode.OK)
            {
                //  it's at least in some way responsive
                //  but may be internally broken
                //  as you could find out if you called one of the methods for real
                MessageBox.Show(string.Format("{0} Available", url));
            }
            else
            {
                //  well, at least it returned...
                MessageBox.Show(string.Format("{0} Returned, but with status: {1}", url, response.StatusDescription));
            }
        }
        catch (Exception ex)
        {
            //  not available at all, for some reason
            MessageBox.Show(string.Format("{0} unavailable: {1}", url, ex.Message));
        }

    }
