After installing SP2, the owa page will not load.  Outlook works fine.  I have checked container and user permissions, reinstalled IIS and CAS, and re-created the virtual directories.  Anyone have any ideas as what to try?  Here is the OWA error message:

User host address:

Exception type: Microsoft.Exchange.Clients.Owa.Core.OwaInvalidConfigurationException
Exception message: Object reference not set to an instance of an object.

Call stack
Microsoft.Exchange.Clients.Owa.Core.Global.ExecuteApplicationStart(Object sender, EventArgs e)

Inner Exception
Exception type: System.NullReferenceException
Exception message: Object reference not set to an instance of an object.

Call stack
Microsoft.Exchange.Clients.Owa.Core.Configuration.CheckPublicFolders(ADSystemConfigurationSession session, ADObjectId[] pfdbIds, Boolean& allLegacy, Boolean& allLater)
Microsoft.Exchange.Clients.Owa.Core.Configuration..ctor(ADSystemConfigurationSession session, String virtualDirectory, String webSiteName, ADObjectId distinguishedName, Boolean isPhoneticSupportEnabled)
