We have a user who cannot connect to our Exchange 2007 webmail using the URL. If he uses the IP, it connects. This is only on 1 laptop. On the other computers in his home, the URL works. The laptop is running Windows 7, the other computers are running XP.
The site loads from the URL from another outside source on a different ISP fine (Server 2008), but does not load for another user on the same ISP as the first useing the URL (Also XP).
All machines running IE 8.
This only affects our websites, none other that we are aware of and only seems to be HTTPS.
