ASP.Net/IIS uprawnienia lub problemy z konfiguracją

Mamy farmę sieci Web z 3 serwerami, na których działa aplikacja ASP.Net 3.5 na IIS6, serwer Windows 2003. Właśnie zainstalowaliśmy aktualizację aplikacji i dwa z trzech serwerów działały prawidłowo, ale trzeci zaczął mieć problemy od razu. Podczas próby uruchomienia witryny w dziennikach widzimy ten wyjątek:

System.IO.FileLoadException: Could not load file or assembly 'System.EnterpriseServices.Wrapper.dll' or one of its dependencies. This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1)

File name: 'System.EnterpriseServices.Wrapper.dll' ---> System.Runtime.InteropServices.COMException (0x800736B1): This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1)

i od teraz:

Do tej pory próbowałem:

• Ponowne uruchamianie usług IIS
• Uruchom ponownie serwer
• Zainstaluj ponownie .NET Framework
• kopiowanie EnterpriseServices.dll i EnterpriseServices.Wrapper.dll do katalogu html/bin
• Uruchamianie aspnet_regiis -i [list][*]daje błąd: Błąd podczas tworzenia kontekstu aktywacji dla C: \ WINDOWS \ assembly \ GAC_32 \ System.Data \ 2.0.0.0__b77a5c561934e089 \ System.Data.dll. Komunikat pomocy dotyczący błędu: Odmowa dostępu.

Więc trochę utknąłem. Jakieś pomysły?
