The Solution is great, but has some serious holes built into the Iprism. The Iprism can be bypassed with enough skill and does not play well with NT. If a user logs off a system and another person logs onto that machine than the websites appears under tne previous user until the authentication times out. Login off your machine won't log you off Iprism and a reboot won't break the authentication, you must log off the Iprism, so Book mark the login screen. I hope you don't have a second shift or log in late. The processor is 500Mhz with 128 Mb of Ram and can BOG DOWN at times causing delays for users. The Iprism is user friendly and feature rich, and compared to other filters it is superior, but needs some fine tuning. the Tech support has some good people, but your experience will depend on who you get.....
