Cross Domain WebService Call in Asp.net using Jquery

Hi,

Requirement is:
a) webservice(Suppose Webservice.asmx) is hosted on one server, suppose www.xyz.com
b) On www.xyz.com domain, a javascript file is present who accesses this webservice.
c) On www.test.com , the javascript file of www.xyz.com is included in html page.
d) When i run html page of www.test.com site, i got jquery parsed error.
e) When i include same javascript file in html page of www.xyz.com domain then it works fine.
f) Both applications are running on IIS6.0

I implemented it using using jquery with jsonp.

var baseurl = "http://localhost:50249/WebService.asmx";
$.support.cors = true;

    $.ajax({
        type: 'POST',
        //crossDomain: true,
        dataType: "jsonp",
        jsonpCallback: 'jsonCallback',
        contentType: "application/json; charset=utf-8",
        url: baseurl + "/HelloWorld",
        data: '{}',
        dataType: "json",
        success: function(data) {
            alert(data.d);
        },
        error: function(err) {
            alert(err.statusText);
        }
    });

Getting statusText="No Transport".
status=0
Following Error in browser console.
"Origin http://localhost:64048 is not allowed by Access-Control-Allow-Origin. "


Note: In IE8 it is working fine.

Can anyone please let me know how to access cross domain webservice ?

Thanks in Advance.
