Buonasera, ho sviluppato un'applicazione web C#, VS2010, FWK4.0 che integra alcune classi racchiuse in una dll.

in fase di rilascio su un server di test (windows Server 2003 SP2) non riesco a navigare l'applicazione a causa del seguente errore

Could not load file or assembly 'Cryptography' or one of its dependencies. Access is denied.

X evitare problemi ho dato Full control sul path dell'applicazione a "Everyone".

Ma il problema persiste.

Altri dettagli dell'errore sono questi ( al momento ometto lo stacktrace)

Exception Details: System.IO.FileLoadException: Could not load file or assembly 'Cryptography' or one of its dependencies. Access is denied.
