Access of documents from sharepoint folder

I am trying to access documents from a sharepoint site , I am accessing from client machine , Sharepoint in install on another machine (server) by using microsoft.sharepoint.client.dll
 

using (ClientContext clientContext = new ClientContext("http://sharepoint/sites/SPTest"))
                {
                    clientContext.Credentials = new NetworkCredential("Administrator", "Admin13", "sharepoint");
                    Web web = clientContext.Web;                    
                      Folder folder = web.GetFolderByServerRelativeUrl("Documents");
                      clientContext.Load(folder);
                      clientContext.ExecuteQuery();                    
                   
                        foreach (Microsoft.SharePoint.Client.File file in folder.Files )
                        {
                            MessageBox.Show(file.Name);
                        }
                    }
