I've published Exchange 2007 owa with Forefront TMG. It was working perfectly well until I decided to create another listener for autodiscover NTLM authentication. autodiscovery is working great now, but owa seems to be broken. The strange thing is that from one of my machines it works perfectly well as it always has. Which leads me to believe that this machine is in some rule somewhere that is giving it extra access permission. I also noticed that the computer that it's working for shows the owa site as in the local intranet, where as on the other computers I can't get them to recognize the site in the local intranet. I've attached a file that has TMG logs from the working computer and one that doesn't. Any ideas? Thanks!
