Answer 1

I haven't been able to completely replicate your issue on Server 2008 R2 with SQL Server 2008 since everything works okay in my environment per your instructions. I did have the same error when I had mistyped the name of my app pool in IIS but everything fell into place when the app pool name was corrected. I also was able to add the ASP.NET v4.0 identity as well.

I may be reaching a little here, but did you right-click and run SSMS as an administrator? This may not be an issue with UAC on Win 7 but can affect things on the Server versions of Windows. Also, you might try to see if you have the same problem when modifying an NTFS ACL. You should be able to add the app pool identity in an NTFS ACL using the same IIS APPPOOL\ASP.NET v4.0 name as in SQL Server. If you get different behavior, it might have something to do with SQL Server. If not, then there might be a service that's not running on your Win 7 desktop that you need to resolve the app pool identity.
