Internet connectivity issue

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.

If that outside user pings the Exchange server by FQDN, does it resolve to the correct IP address?

No, if they ping it, it does not resolve.

Is the Win7 laptop (the one that doesn't work) using the same DNS server(s) as the other machines in his home?

No idea what it's useing for DNS. They are all connected to the same router using DHCP. I would ask the user, but it would be easier to give him a new laptop then to try to get any useful information out of him.

We've all dealt with people like that at one time or another.  If they're getting DNS through DHCP, they should all be using the same servers, but there's a chance he's hard-coded the DNS server on the Win7 box and used the wrong address.  Good luck finding out for sure.  :)

Whatever the issue was, it resolved itself. I have the laptop now, and nothing was hardcoded. No way to tell now what was causing the issue now.
