I seem to have run into to a wall that I can't get passed. I have moved an Episite to IIS 7.5 from IIS 6 and also upgraded from cms 5 to 6. I now get the following exception when I start it. I am certain that there is something missing in my web.config but I can't for the * of it figure out what it is. All help is greatly appreciated.

System.TypeInitializationException: The type initializer for 'EPiServer.Security.PrincipalInfo' threw an exception. ---> System.NullReferenceException: Object reference not set to an instance of an object.

Ensure that you have migrated your web.config file correctly. On the assumption that your applicaiton pool is running in Integrated managed pipeline mode then ensure that the <httpModules> section is correct.

If you change your application pool managed pipeline mode to Classic and all works OK then you have a problem with your web.config file.

Ps a good place to start when checking web.config is for the existence of <add name="InitializationModule" type="EPiServer.Web.InitializationModule, EPiServer" /> in the <httpModules> section.

Try reinstalling IIS and see if you still get the problem.
