Hi all

I am having one web service where in at a time of calling one webmethod

through client application i am continuously getting following error :-

The underlying connection was closed: An unexpected error occurred on a

receive
I tried with adding following code in reference.cs file :-
protected override WebRequest GetWebRequest(Uri uri)
{
HttpWebRequest webRequest = (HttpWebRequest) base.GetWebRequest (uri);
webRequest.KeepAlive = false;
webRequest.ProtocolVersion=HttpVersion.Version10;
return webRequest;

}
As well as i tried with increating connection timeout property in
default web side's property in IIS. But of no luck.

Can some one shed some light on this.
