IIS7 and Vista

With IIS 5 and 6 I could access the local web server on my machine by typing
my machine's name in the browser. With IIS7 in Vista Ultimate the local
machine name does not work.
The local machine IP works. Using "localhost" works. Even using my machine
name from another computer works but not from my computer. Pinging my
machine name resolves to the proper IP.

Any ideas how to get this working?

Thanks
