scriptresource.axd 404 error in asp net 4 application - webresource works fine though

Question

Hey everyone, I have a .net 4 application that i just deployed to production. The app loadas fine, except my referenced js files arent loading properly. Using fiddler I found that the ScriptResource.axd calls are returning 404 errors.

Heres the kicker, the page is also making a call via WebResource.axd, and that request works just fine.

Any ideas what I can check for? Were running IIS7. It is load balanced, but we have machinekeys in the config. I added an httpHandlers section for scriptresource.axd.. but Im still having the same issue.. stumped...

Update - we think ou websrver has no idea what an axd file is. Is there any install for .net that will install the axd mappings in iis?

Looks like handlers needed to be added to system.webserver, per this blog: http://geekswithblogs.net/lorint/archive/2007/03/28/110161.aspx

<system.webServer>
  <handlers>
    <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
  </handlers>
</system.webServer>
