NAV Webclient IIS Rewrite/Redirect http://host to http://host/dynamicsNAV90/Webclient

i have changed the binding to port 80 for the Dynamics NAV webclient , but now i just get the default.htm's message: "is is the default page for the site container for the web site of the Microsoft Dynamics NAV Web Server Components" page.

how can i redirect it to go straight to DynamicsNAV90/Webclient?

I have tried using the url rewrite and http redirect in IIS but i cannot get it to work. Any help would be greatly appreciated!
