Known Limitations of ADC
In SEP 11, Application and Device Control functions only on 32-bit Operating Systems. ADC is not possible on 64-bit computers. ADC cannot block burning to CD/DVD drives, though a workaround may be possible. ADC cannot block files accessed via NetBIOS. ADC shares drivers with Network Threat Protection, SEP's firewall component. ADC will only function if the NTP component is also installed
