You can use the XMLHTTP object which comes with MSXML, (see http://support.microsoft.com/default.aspx?kbid=290591) or if you prefer an OCX, try the Internet Transfer Control.

Surely its not that difficult to translate that little bit of js:
function XMLHTTPButton_onclick() {
    var DataToSend = "id=1";
    var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    xmlhttp.Open("POST","http://<%=Request.ServerVariables("Server_Name")%>/Receiver.asp",false);
    xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
    xmlhttp.send(DataToSend);
    alert(xmlhttp.responseXML.xml);
}

delete all trailing ;
var -> Dim
new ActiveXObject -> CreateObject
put Call in front of the next 3 lines
alert -> MsgBox

voila!

1. use the "XMLHTTP" object from VB, not the "ServerXMLHTTP" object
2. do you really have a space here "application/x-www-form- urlencoded"?
3. is there anything in "DataToSend" variable
4. have you looked at the webserver logs to see what the request looks like from that end? this may give additional clues.

Have you tried a GET instead of a POST? Are you actually POSTing anything?
