As a SharePoint developer, I find that I spend a lot of time using one of the Server Operating Systems (2003/2008). Interestingly enough a registry tweak is needed before you can actully do any real testing (like using host headers).
The solution for me and one of my colleagues turns out to be this old known issue

and

I would only recommend to disable the Loopback checking for developing environments.
Disable Loopback Checking
- open regedit
- Find HKLM\System\CurrentControlSet\Control\Lsa
- Create a new DWORD value called DisableLoopbackCheck and give it a value of 1
- Restart the computer
