/Shibboleth.sso/Status throws 404 on one host but not another

[Scott Conklin]

I have read over just about google post and every message in this list
regarding 404 issues when using Shibboleth with IIS

It seems I can get Shibboleth to work on only one host/site in IIS which is
not the one I want to use.
I have one IIS webserver running about 20 web applications pointing to
unique path/resources.

Our corporate website referred to here as  mycompany.com with the following
Site ID
set in the <ISAPI  section like so
<Site id="3" name="www.mycompany.com" />
works
BUT one of our client sites that has subdomain configured to run one of our
web applications  at this ID
<Site id="34" name="clientsite.mycompany.com" />
does not work

I get a 404 on all handlers when testing it.

https://clientsite1.mycompany.com/Shibboleth.sso/Status

1) I am confident about the siteID and have tried it with and without
scheme and port set.
2) I have cycled IIS and Shibboleth in Services after each change
3) I have tripled check that the RequestMap -> Host entry match by name
<Host name="clientsite1.mycompany.com " >
           <Path name="secure" authType="shibboleth" requireSession="true"/>
</Host>
5) The <applicationDefaults>  looks normal with the default entityID set to
the same url

  <ApplicationDefaults entityID="
https://clientsite1.mycompany.com/shibboleth"
        REMOTE_USER="myID email eppn subject-id pairwise-id persistent-id"

cipherSuites="DEFAULT:!EXP:!LOW:!aNULL:!eNULL:!DES:!IDEA:!SEED:!RC4:!3DES:!kRSA:!SSLv2:!SSLv3:!TLSv1:!TLSv1.1">

4) I uninstalled Shibboleth ver 3.2.3.1 and upgraded to 3.3.0.0
5) I see no errors or anything of consequence in the var/log files

After hours of trying, I really don't know where else to look to
troubleshoot why this is happening.
Can anyone point me in the correct direction or tell what I should do to
debug this?
