HTTP Error 500.1002

Hi I get this error while using iisnode.

<configuration><system.webServer><!-- indicates that the hello.js file is a node.js application 
     to be handled by the iisnode module --><handlers><add name="iisnode" path="app.js" verb="*" modules="iisnode" /></handlers><!-- use URL rewriting to redirect the entire branch of the URL namespace
     to hello.js node.js application; for example, the following URLs will 
     all be handled by hello.js:
         http://localhost/node/express/hello/foo
         http://localhost/node/express/hello/bar
     --><iisnode devErrorsEnabled="false" /><rewrite><rules><rule name="hello"><match url="api/*" /><action type="Rewrite" url="app.js" /></rule></rules></rewrite><!-- exclude node_modules directory and subdirectories from serving
     by IIS since these are implementation details of node.js applications --><security><requestFiltering><hiddenSegments><add segment="node_modules" /></hiddenSegments></requestFiltering><authentication><anonymousAuthentication enabled="true" userName="Administrator" password="XXXXXXXXXXXXXXX" /></authentication></security><directoryBrowse enabled="true" />    </system.webServer><system.web><identity impersonate="false" /></system.web></configuration>

That is my web.config. Someone please help. Thanks Ender.
