How To Block Backdoor To Internet

Want to close a backdoor to the internet on a Windows 2000 terminal server.
Users can right mouse click on the desktop, then select New and then select
shortcut. The shortcut wizard starts.

If they type a URL in the shortcut line, it will create a shortcut to the
web site.
All they have to do is double click on the shortcut to get to the web site.

In the GPO IExplore.exe is blocked from use. Double click on the Internet
explorer icon, and the user is told they do not have permissions to run
IExplore.exe. But if they create a short cut to the web site, it opens just
fine.

How do I block this back door?
 
Hello Charlie,
In the GPO IExplore.exe is blocked from use.
Click to expand...

IMHO a better solution would be to create a user group "NoSurf" and
give them an internal non existing proxy server address via GPO
(UserConfig/Windows/Internet Explorer/Connection/Proxy). IE would be
still working for internal purposes and your problem with shortcuts
would be solved, too.

Hello,

I suggest you refer to the following article to restrict IE from running
via Group Policy. My test steps are as follows, client is XP and the server
is win2k3:

1. Put the computer account called TEST to the OU you want to disallow the
user to use IE.
2. Open the GPO of this OU
3. Locate to the following policy:
4. Computer Configuration\windows settings\security settings\software
restriction policies
5. Create a new policy
6. In Additional Rule->New a path rule
7. Put "%programfiles%\internet explorer\iexplore.exe" in the path, set
the security level to disallow.

NOTE: this policy will take effect when the client restarts.

More information, please refer to the following article:
