That would be the 403...from ISA not IIS

No /*.

If I https with the IP, I get the Cert warning (self signed cert so I get a 
warning).  If I go past the warning, I get the 403 Forbidden error.  What is 
letting me into the IP without a URL name?  Shouldn't ISA refuse the connection 
altogether (no cert warning) if I don't use the URL for webmail or ActiveSync 
access?

ISA has no vulnerabilities unless you have configured it wrong. You don't have 
a /* in your publishing rule do you?

It;s likely your scanner.....

We have our ISA 2006 Server setup for webmail & ActiveSync to our Exchange 2007 
server using a Listener.  However, when we do a vulnerability scan for PCI 
compliance, the IP for this listener on the ISA server is coming up with an SSL 
V2 vulnerability.  Now, I have done all the stuff (regedits) I need to do on 
the Exchange 2007 server to disable SSL V2, but I am still coming up with a 
vulnerability on a scan.

Could it be that when accessing Port 443 on the IP in question, the request is 
forwarded somewhere else when the Webmail/Activesync URL 
(mailserver.domain.com/owa) is not specified (i.e. not to the Exchange Server 
but the ISA IIS Server?).  I don't see anywhere else where Port 443 could be 
forwarded.  Any suggestions?
