My Code:

FileInfo fileinfo = new FileInfo(@"\\10.16.20.70\website.com\wwwroot\im_online.png");

           Response.Clear();
           Response.ClearHeaders();
           Response.ClearContent();
           Response.AppendHeader("Content-Disposition", "attachment; filename =im_online.png ");
           Response.AppendHeader("Content-Length", fileinfo.Length.ToString());
           Response.ContentType = "application/download";
           Response.WriteFile(fileinfo.FullName);
           Response.Flush();
           Response.Close();
           Response.End();

Error:
Logon failure: unknown user name or bad password.

How to set username and password for my remote server to download the file in it?.
