So, I have one simple question..... In my company I have fiew power users that have wright to use Internet thrue ISA server. But they are so good to their coleques thath they provide them username and passwords for logg in to their local machines so that the coeques can use internet as well as they do. How I can prevent multiply log in on to ISA server to prevent sharing of user name and pass between coleques in order to prevent Internet use. Any recomend....... 10x in advance
