Answer 10

I don’t think we have enough information to be useful. What is a security context (identification) during a Delete call? Is the application personifying the end user? If so, how are they authenticated? If in Windows / Active Directory you need to check user permissions for a specific file. If by Forms login you probably should not impersonate and verify that the AppPool security context has the appropriate permissions.
