when I go to https://servername/exchange
I get a IE page cannot display the webpage. My OWA was working just fine until today when I had to become PCI compliant and make a couple changes with disabling forms based authenication and Set the UseHostName Property: cscript adsutil.vbs set w3svc/x/UseHostName true. Now OWA doesn't work internally or externally.
I've tried reversing both changes, but OWA still won't work.
