Opret hjemmeside i IIS6 via JS script

Jeg har følgende script, det virker ganske fint !!!
Men hvordan tildeler jeg sitet til den application pool der hedder "sites" ?

var Web          = "test";                  //Sub navn
var strRRsufix    = ". IN A 172.16.0.2";      //ip address of the IIS server
var ServerBinding = "172.16.0.2:80:";      //ip address and portnumber
var DNSroot      = ".domain.com";
var strDomain    = "domain.com";
var sRootDir      = "d:\\documents\\test";      //place of the site

CreateWeb(Web + DNSroot,sRootDir,Web);

function CreateWeb( sHostName, sRootDir, comments )
{
var oWeb = GetObject("IIS://localhost/W3SVC");
oWeb.GetInfo();

//looks for the first free website and create it
var Index = 1;
var cont  = 0;
while( cont == 0 )
{
  try
  {
    var webobj = GetObject("IIS://localhost/w3svc/" + Index);
  }
  catch( e ) 
  {
    if( ( e.number & 0xFFFF ) > 0 )
    {
      cont= 1;
    }
  }
  Index = Index + 1;
}
Index = Index - 1;
WScript.Echo( "Next Index: " + Index );
WScript.Echo("creating web " + sHostName);
oServer = oWeb.Create("IIsWebServer",Index);

//Configure the new server
oServer.DefaultDoc        = "index.asp, index.aspx, index.html, index.htm, index.php";
oServer.ServerComment    = comments;
oServer.ConnectionTimeout = 600;
oServer.ServerBindings    = ServerBinding + sHostName;
oServer.SetInfo();
var fs    = new ActiveXObject("Scripting.FileSystemObject");
if( !fs.FolderExists( sRootDir ) )
  var foldr = fs.CreateFolder(sRootDir);

//Create virtual root directory for the new site
oServer  = GetObject("IIS://localhost/w3svc/" + Index );
var oVdir = oServer.Create("IIsWebVirtualDir", "ROOT");

//Configure the virtual root directory
oVdir.Path        = sRootDir;
oVdir.AccessRead  = "True";
oVdir.AccessWrite  = "False";
oVdir.AccessScript = "True";
oVdir.SetInfo();

//Starting the website
WScript.Echo("starting web " + sHostName + " " + Index);
oServer.Start();

} //end function
