Hows about a written policy backuped by a 9mm :) J/K From my experience, when you take a user out of the Admins group, they are not permitted to do all certian functions, like mess with netwrok settings, add drivers, hardware, software. ect,ect. Unfortunelty i cant do this because i work for a software company that has a bunsh of programmers, and they need to be admins on there machines to do there jobs, as you can image this makes my job of controlling what they are doing on these machines a bit problematic, but if you have users that do the same taks everyday, and would nver need toinstall a device driver, that it would work for you. I would get to know the run as command well, if you are going to do this. As far as ISA goes I control access based on domain users for access to the internet, this lets me easily block sites, content redirect users that go to unarthorised sites back to the company's intranet site, that explains the internet policy (I love this one)In short, i would setup your ISA server to control access based on your domain user accounts, this is alos helpful when you need to read the logs, all access will show up as username\domain, as long as you have NO Anonymous rules in effect on your ISA server.
