Yeap it's the AppPool identity, which is called "ASP.NET 4.0 x64" for my case. The NTFS permission is setup like v1.3, which works. Don't know why this one is failing when procmon did not report any Access denied errors.

You should be able to add the account or the IIS_IUSRS group to the NTFS permissions on those directories to get it working. Cheers, Drew
