title: ASP.NET web application working incorrectly in IIS 7 (Windows Server 2008)
body: <p>I have an ASP.NET web application that is not working correctly once deployed to IIS 7 on a Windows server 2008 box.  The particular page is using an update panel and hides/shows drop down lists based off of a selection in a drop down list.  The page is working perfectly locally using Cassini (the local webserver used by Visual Studio 2008), but loses the items from the drop downs and does not show and hide the controls upon callbacks from within the update panel.</p>
  
  <p>I've googled around and have a suspicion it may have something to do with the Integrated vs. Classic pipeline in IIS 7.  It's currently using the DefaultAppPool(Integrated). Can someone help me figure out what I should do???</p>
