Hi, I'm new. I found this guide http://searchwindowsserver.techtarget.com/tip/0,289483,sid68_gci1099219,00.html (Windows Server Tips: Block Internet Explorer Web surfing via Group Policy) on the site whilst trying to find a way to block internet access for certain users using Terminals Services. I followed the guide and added other rules to the policy which work, but I can still get on to the internet on my test user profile. I also ran rsop.msc on the profile and could see my proxy settings in place. Can anyone advise why it seems to be ignoring the proxy settings?

Thanks. We'll let you know when a new response is added.

This is what you followed:

Have you ever want to block a user’s ability to surf the Web using Internet Explorer? Here’s how you can do that!

Use a Group Policy Object (GPO) that forces Internet Explorer to use a proxy server with an address of 0.0.0.0 for port 80 requests. Then create another policy that states a user is not able to change the proxy server address in Internet Explorer. Both policies are applied to the user and not the computer. These settings tell Internet Explorer to call over to the non-existent proxy server for all internet requests. When the non-existent server does not respond, Web surfing is stopped.

The policy settings are located in the following locations in the GPO:

User Settings –> Windows Settings –> Internet Explorer Maintenance –> Connection
Then open the Proxy Settings window and add 0.0.0.0 for port 80.

User Settings –> Administrative Templates –> Windows Components –> Internet Explorer
Then set Disable Changing Proxy Settings.

Good luck — and backup before you try this!

I normally do the same thing but replce the proxy settings ip with the local host’s like so:

User Settings –> Windows Settings –> Internet Explorer Maintenance –> Connection
Then open the Proxy Settings window and add <b>127.0.0.1</b> for port 80.

User Settings –> Administrative Templates –> Windows Components –> Internet Explorer
Then set Disable Changing Proxy Settings.

Give that a shot and let me know if that works out. I always thought 0.0.0.0 was null.
