Go4Expert - service unavailable

I am trying to invoke a webservice from javascript.

When I work locally (html and javascript on my PC) calling the webservice on a remote pc, it is successfully working. However, when I put the htm & javascript on another pc and I open the page using ip of other pc, I am getting "Service unavailable" error!

Do you have any idea?

The following is the code I am using:

HTML Code:

<HTML>

<HEAD>

<SCRIPT language="JavaScript">

function init()

{

service.onServiceAvailable = alertReady;

service.useService("http://webservices.codingtheweb.com/bin/qotd.wsdl","quote"); 

}



function alertReady() {

alert("Ready");

}



function getQuote() {

service.quote.callService(onmyresult,"getQuote");

}



function onmyresult(result)

{

if (!result.error) {

service.innerHTML = result.value;

}else{

service.innerHTML = "Error: " + result.errorDetail.code + " " + result.errorDetail.string + " " + result.errorDetail.raw;

}

}

</SCRIPT>

</HEAD>

<BODY onload="init()">

<button onclick="getQuote()">Get Quote of the Day</button> 

<div id="service" style="behavior:url(htc/webservice.htc)"></div>

</BODY>

</HTML>
