At my company, we have set up ISA Server 2003 with a list of banned sites, in particular a website where one of our employees is downloading 100Mb videos. The website is on the banned list, spelt right, and when I try to access it via my own PC, its blocked. But the employee who was downloading videos is still able to access the banned sites. He's using DHCP, and all computers have to go thru the ISA server to access the internet. How is this possible?

Dunno, But you obviously have a management problem. What else are employees doing which you do not want them to do? Conversly, what are they not doing which you're paying them to do? M2 If at first you don't succeed, you're about average.

Well he's the main priority at the moment, he's downloading about 500Mb a day and saving it onto the server. The work he's not doing is dealing with the sale of millions of pounds worth of stocks and shares a day

I rest my case. M2 If at first you don't succeed, you're about average.

Please post the stocks that this guy is responsible for so I know where not to put my investments Ha! K then, sounds like that comp might be in the wrong group.
