code security

Hi,

I'm having some trouble with setting code security settings in the .net framework configuration. I'm using our corporate network and so want to allow everyone to run an assembly off the internet. I don't want to have to go around configuring everyones machine, so I thought the best thing to do would set the enterprise policy. Where do i set this though so that the effect trickles down to all the users machines?

Also, has anyone had problems with setting code securities? I've been able to experiement on my development machine a bit as i have local admin(so i can set the machine security policy). I managed to get an assembly working from the internet. But I try to do the same steps for another and can't get it working at all! I try to undo what I did for the original, and I can't undo it!!! Setting the security permissions seems a right pain.

Can anyone help?

Cheers
Nick
