[santhescript01]

Hi All,
I have an windows application created in C# &it is running fine on several of our customer.
It does a httpWebrequest in the background.
Everything was working fine but some customer are facing
"The Remote server returned an error :(407) Proxy Authentication Required "


{
WebRequest request = WebRequest.Create("http://TServer.com/WebForm2.aspx");
string Text = "Question";
request.Method = "POST";
string postData = "TextBox1="+Text;
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = byteArray.Length;
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse response = request.GetResponse();
Console.WriteLine(((HttpWebResponse)response).Stat usDescription);
dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
Console.WriteLine(responseFromServer);
reader.Close();
dataStream.Close();
response.Close();
}

Instruct them to get their network admin to fix it up...its their proxy which isint allowing them to let the website go ahead,
If they are using a authentication to access the internet, then you will have to use the credentials to do so.

Had a similar issue and we ere blaming the website...until we found out that it was the school itself playing funny.
