If you are getting that "Page cannot be displayed" error
-- the one that comes up instantly and annoyingly -- then you must be
using MSIE. Internet explorer has a known bug that has to do with the way IE does DNS. The way you can tell you have
this problem is that the error comes up instantly. You know the browser
didn't actually check for the page. There is considerable discussion on
this topic in the Microsoft Knowlege Base. Also here:

We hear tell that there are several other ways MSIE can give this error. Rest assured that this
is most definitely a browser issue.
The MS KnowlegeBase has the whole scoop. Consult that for details.
Or just use Firefox or Opera. :)
