In the far 2007 I wrote a post about the connection tab disabled in IE6. Now after some years even here at the customer everything is migrated up-to IE8. The result is that the Connections Tab is enabled but not the “LAN Settings” button and its items in child window (Automatic Configuration and Proxy server) are disabled.

- Take the content from the PDF and copy-paste into a .reg file.
- Close all instances of IE.
- Double click on it.
- Reopen IE
