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?
