I have developed a page which can upload files. When I am using it in localhost iis server it works perfect but when I publish it to IIS remote server only can upload 100KB and over of this size the progress would be stacked.

Need your help

Thanks in advance;

What I have tried:

if (file != null && file.ContentLength > 0)
                try
                {
                    string tm = DateTime.Now.Ticks.ToString();
                    file.SaveAs(Server.MapPath("~/Documents/" + tm + file.FileName));
                    string paths = "Documents/" + tm + file.FileName;
