i've located my application on IIS 6. the vista which i desired to browse gets fetched within the browser however the css and scripts aren't being made .

<link href="<%= Url.Content("~/Content/Tree.css")%>" rel="stylesheet" type="text/css" />

in by doing this i've because of the path.

The link tag is correctly defined. You're while using Url.Content method having a relative path in the site root that will properly consider the virtual directory that could be added in when hosting under IIS.

I would suggest you searching at FireBug to determine why the road isn't found and what response does the server send once the CSS is fetched. May be the file missing? Or perhaps is there another status code came back?
