How to configure DNS on Server 2012 to allow hosts without "extension"?

view story

http://serverfault.com – I'm using Windows Server 2012 as my DNS server. I'd like to have the address http://intranet to point to I'm not able to reach this. If I create a Forward Lookup Zone, for example Local and add a host (A-record) there named "intranet", navigating to http://intranet.local goes to the right place. What I want is to get rid of this .local extension. How can I achieve this? I had it working in Server 2008, but after reinstalling the system I can't remember how I had it done. (HowTos)
