After following the instructions here

How To Implement URL rewriting with UrlRewriter.Net?

I'm getting a Referenece Exception -->

I have added the tag because I have read that this error most of the times pops up when you don't have the rewriter section specified in your web.config. So what can be the problem now? I'm trying to run this on an IIS 6.0 (windows 2003) server.

This module won't be able to run on IIS 6.0 since the URLRewrite module 2.0 is only available for IIS 7.0 as an extension.
