I did tried on 3+ machines and all browser I can get (IE, FF, Chrome, Safari) with no luck.
However, I solved the problem. For some reason, I start the IIS "Default Web Site" which makes http://localhost works. Then I browse to localhost/CFIDE/admistrator and everything works!!! But it works for localhost only, if I put the real IP or the real url, it doesn't work.
Anyone has any clue?
