host nodejs chat application with iis node

I have developed a chat application with nodejs. Currently, I am using the chat server hosted from a command prompt. This chat server is not bound to any domain name. I want it to bind to a domain with IIS. I have also tried to install IIS Node but could not get through. I have all my chat code in chatroom.js file, there is no HTML file to be rendered. I am not clear how to host it with IIS Node. I am using IIS 8 on Windows 8. The error I am get when hit the URL : http://localhost:3004/chatRoom.js

HTTP Error 500.21 - Internal Server Error Handler "iisnode-socketio" has a bad module "iisnode" in its module list

Below is my web.config :

<configuration>
 <system.web>
    <compilation debug="true" targetFramework="4.0"/>
  </system.web>
  <system.webServer>

    <!-- indicates that the server-faye.js and server-socketio.js files are node.js applications 
    to be handled by the iisnode module -->

    <handlers>

      <add name="iisnode-socketio" path="chatRoom.js" verb="*" modules="iisnode" />
    </handlers>

    <!-- indicate that all strafic the URL paths beginning with 'socket.io' should be 
    redirected to the server-socketio.js node.js application to avoid IIS attempting to 
    serve that content using other handlers (e.g. static file handlers)
    -->

    <globalModules>
        <add name="iisnode" image="C:\Program Files (x86)\iisnode-express\iisnode.dll" />
    </globalModules>

    <rewrite>
      <rules>
       <clear />
        <rule name="cdw">
          <match url="/*" />
          <action type="Rewrite" url="chatRoom.js" />
        </rule>
      </rules>
    </rewrite>

    <!-- disable the IIS websocket module to allow node.js to provide its own 
    WebSocket implementation -->

    <webSocket enabled="false" />

  </system.webServer>
</configuration>

node server side code looks as follows :

var express = require('express'),
    http = require('http'),
    app = express(),
    server = http.createServer(app),
    io = require('socket.io').listen(server),
    Room = require('./room.js'),
    defaultValues = require('./default.js'),
    _ = require('underscore')._;
var request = require('request');
//require('request').debug = true; // uncomment for debugging

app.use('/', express.static(__dirname + '/public'));

server.listen(process.env.PORT);

app.get('/', function (req, res) {

    res.sendFile(__dirname + '/public/indexroom.html')
});

Please let me know if I am missing anything.
