Issues with Web.config in IIS 7 (Vista) and Modules

[mazdotnet]

Hi,
I'm using UrlRewriter.NET in my project which is causing problems when
in Vista (same code works fine on Windows XP). I'm going by the
example in Scott's Blog http://weblogs.asp.net/scottgu/archi...h-asp-net.aspx.
In Vista when I press F5 or Control F5 I get an error message saying

HTTP Error 500.19 - Internal Server Error
Description: The requested page cannot be accessed because the related
configuration data for the page is invalid.

Error Code: 0x800700b7
Notification: BeginRequest
Module: IIS Web Core
Requested URL: http://localhost:80/UrlRewrite_HttpModule2/Default.aspx
Physical Path: C:\inetpub\wwwroot\UrlRewrite_HttpModule2\Default. aspx
Logon User: Not yet determined
Logon Method: Not yet determined
Handler: Not yet determined
Config Error: Cannot add duplicate collection entry
Config File: \\?\C:\inetpub\wwwroot\UrlRewrite_HttpModule2\web. config
Config Source: 31: <remove name="ScriptModule"/>
32: <add name="UrlRewriter"

33: <add name="ScriptModule" preCondition="managedHandler"
type="System.Web.Handlers.ScriptModule, System.Web.Extensions,
Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/></
modules>
My configration file contains the following sections
<configSections>
<section name="rewriter" requirePermission="false"
type="Intelligencia.UrlRewriter.Configuration.Rewr iterConfigurationSectionHandler,
Intelligencia.UrlRewriter"/>
......
httpModules>
<add name="UrlRewriter"
type="Intelligencia.UrlRewriter.RewriterHttpModule ,
Intelligencia.UrlRewriter"/>
<add name="ScriptModule" type="System.Web.Handlers.ScriptModule,
System.Web.Extensions, Version=3.5.0.0, Culture=neutral,
PublicKeyToken=31BF3856AD364E35"/></httpModules>
........
<modules runAllManagedModulesForAllRequests="true">
<remove name="ScriptModule"/><add name="UrlRewriter"
type="Intelligencia.UrlRewriter.RewriterHttpModule "/>
<add name="ScriptModule" preCondition="managedHandler"
type="System.Web.Handlers.ScriptModule, System.Web.Extensions,
Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/></
modules>

So it complains that we have duplicate module sections? Any idea how I
can enable Integrated ..NET mode on this? I tried using

C:\Windows\System32\inetsrv>appcmd.exe migrate config "Default Web
Site/UrlRewri
te_HttpModule2"
ERROR ( message:Configuration error
Filename: \\?\C:\inetpub\wwwroot\UrlRewrite_HttpModule2\web. config
Line Number: 15
Description: Cannot add duplicate collection entry
.. )

Which also says the same thing. Can anyone please tell me how I can
get this working in IIS7 on Vista Ultimate?

Thx
Maz
