When you work on a developpement machine, you may need to create several web application or extend existing ones, using  host header (http://company.domain.local, http://extranet.domain.local). Even if you modify the hosts file, you cannot access the sites, either you get 401 or 404 page or you are prompt with the login dialog 2, 3 times before seeing a blank page.

Apparently this is a known issue, you can find the solution in the Microsoft KB896861. To get everything work I just created  a new .reg file and put this:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
"DisableLoopbackCheck"=dword:00000001
