FireFox and Proxy server.
So I setup a proxy server to filter out URL. However I can not find a way to stop user from changing the setting in FireFox. However I can use GPO to automaticly configure the proxy setting for IE and disable user from changing it.
I can uninstall all other browsers and let users to only use IE and deny them from installing any other browsers, but I would not like to go this way since I would like to encourage those to use FireFox. There are also users who prefer using FireFox since they love the tab browsing. I can not use IE7 because these are 2000 Pro clients. I am not even considering upgrading to XP (these are lowend machines,plus no money). So if anyone have any idea that I haven't come up with yet please help me out.
The Proxy server is located in the same network segment. Can I move this server between the Router and Switch so that all traffic must pass through it, even though User can change the setting can the filtering still work?
