c# failed to upload video
<p>This is my code to upload video on server</p>

<pre><code>protected void Button1_Click(object sender, EventArgs e)
{
    if (FileUpload1.HasFile)
    {
        string fileName = FileUpload1.FileName;
        string fileExtension = Path.GetExtension(fileName);

        if (fileExtension == ".flv")
        {
            if (!File.Exists(Path.Combine(Server.MapPath("~/Video"), fileName)))
            {
                string fullFileName = Path.Combine(Server.MapPath("~/Video1"), fileName);
                FileUpload1.SaveAs(fullFileName);
                Label1.Text = "The file has been uploaded";

            }
            else
            {
                Label1.Text = "The file already exist! You must delete old version first in order to upload new version";
            }

        }
        else
        {
            Label1.Text = "The file format is not allow";
        }

    }//else if
    else
    {
        Label1.Text = "please select a file to upload";
    }

}
</code></pre>

<p>Everything is goes well, but when I upload a <code>.FLV</code> file, It returns me an error message on webpage,here is the error code</p>

<blockquote>
  <p>Output: Error 101 (net::ERR_CONNECTION_RESET): The connection was
  reset.</p>
</blockquote>

<p>How can I solve this problem?</p>
