Can't broowse webpages on port 80 after security updates!!!

[Jeremy]

Error message is Page Cannot be Displayed the
webpage is currently unavailable.

I have narrowed the problem down even further in all cases
the problemed systems cannot access webpages beased on
port 80 any other webpages on any other ports work fine.
There is a definate link between one of the security
updates addred recently to handle port 80 attacks which
obviously went wrong.

Another problem I have noticed is that websites requiring
a username and password via a dialog box ie. Windows
athenification simply reappears after entering appropriate
information. I have seen others on this newgroup
reporting the same problem. Both seem to be related.
