Interesting problem...

one of my clients is a library in town.
They are running a program called Fortress 101.
Its a decent security/lockdown program that kind of stops access to things like start -> run etc...

problem is they go to IE and can access the entire hard drive by typing c:\ into the address bar...
any way that I can stop them from accessing the local machine? Ive poked around, not that hard, but I figured this was the first place I could ask. (Id scour the net, but I thought Id save the time since Im at work and put it out)

Thanks in advance
