ISA is set up to require authentication by users, this appears to stop any anonymous connections through ISA. Websense V4.4 configured with Active Directory users, necessary to get per user blocking etc, kills the ISA server Any ideas would be very gratefully received - or alternatively what would be a good alternative to Websense?
