Well, the reg configuration didn't work at all \:\( I guess Microsofot don't realy know their own OS's. According to the guide there should be some keys whicg can't be found and even though i added them it doesn't work. Could be because i have tried it on IE7 and the article refers to IE6 SP1.

So i'm guessing i will have to do it through the FW which is Check Point NG3. It will be a little hard cause i will have to gather all ip's from all computers and build a couple of rules and groups, but that's what they are paying me for, isn't?
