Brad Bemis is right -- other ports (and not just port 80) associated
with IIS _if_ COM Internet Services is enabled are also exploitable.

Look for messages by Todd Sabin in Bugtraq and/or NTBugtraq and/or
VulnWatch and/or Full-Disclosure for more details.

Well, it is the most widely supported default interface that is
vulnerable. It would be a very unusual machine that is vulnerable on
some other port and _NOT_ on 135, so what is the payoff for writing an
exploit (at least a "prrof of concept") that tries other ports?
