Using a proxy...

Dear Experts,

I installed Cyclope Internet Filter in a small server (LAN of only 8 PCs). It works fine when going through the proxy server and everything I want to block is getting blocked. Now, if I change the LAN Settings on the IE (or any other browser) and
uncheck the "Use a proxy server for your LAN", I am able to surf any page. Isn't the user's PC suppose to fail the connection if I uncheck the "Use a proxy server for your LAN" option?

Is there a way to disable the LAN connection button in IE. (Tools > Internet Option > LAN Connections) without using policies. If not, can I block the button to a particular machine?

I don't know much about this, please help!

What you need to try and do is to control this by your firewall if you do not want to use policies. The firewall needs to be told to only accept web traffic from the filter rather than from all Ip addresses.
What is your external firewall/router?

The second option you could use would be to move the clients default gateway from being the router/firewall. this way, if they do not use the filter box, their machines will not know How to get to the internet.

create REG file with this content:
*****************************************************
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Control Panel]
"Proxy"=dword:00000001
*******************************************************

and apply it to the users in login script in silent mode. (or start up script)
this will disable the proxy setting in the explorer.
(it's equivalent to the setting that made by GPO )

to disable the lan setting add the line :
"Connection Settings"=dword:00000001

and by the way you can use the GPEDIT.MSC tool (on XP\w2k)
to set it by GUI on each computer.  
it's under :
administrative templetes -> Windows Components ->internet explorer
don't forget to set the proxy before disable the access  :)
