I would be the last person to suggest that I am an authority on security,
however...
You mentioned that they are running Exchange and IIS.  What I have seen done
before in that situation is that they set the IIS to only respond based on
host header name (if that is the right term), ie: 10.0.0.4/default.htm
woudln't work, but www.domain.com/default.htm would.
I have watched both Retina and Nessus bounce off of those sites with nary a
whimper, when I KNEW that the site was vulnerable to some fairly simple
attacks, because they scan at the IP address, rather than using host header
names in their scans.

Dunno, it may be something to look at.

 almost everyone who replied pointed towards icmp. We have tried running
the
test with icmp disabled. We still do not get a reply on those ports.

Have you carefully looked at some of the buried down setting under your
scanners.  It might simply be that it is expecting a reply from a ping
request before doing the scanning.
