You said (and I quote from further down the thread):

1) The security certificate is from an untrusted certifying authority
2) The security certificate date is valid
3) The name on the security certificate is invalid or does not match the name 
of the site. 

All of these generate a "500" error in ISA.

But Jim, I never saw a "500" error anywhere - if I saw this error message, I 
would have tracked it down in the documentation. My OWA rule work perfectly 
fine.

You haven't followed the advice, books, or articles.
If you had, you wouldn't be seeing the errors you're quoting.
You've been getting the answers to the questions you ask.

Q - Why does ISA produce a "500" error for my OWA rule?

A1 - the certificate installed on ISA must be issued by a CA that is in the 
local machine trusted root store.  This is equivalent to the IE "
The security certificate is from an untrusted certifying authority"
popup.  Install the CA cert in the ISA trusted root store.  If ISA the CA 
certificate installed in the local machine trusted root store, this error will 
stop.  This error will cease if the CA cert is installed in the ISA local 
machine trusted root store. Install the CA certificate in the local machine 
trusted roots store and this error will stop.

A2 - the common name in the certificate does not match the data in the "server" 
field of the "To" tab in the web publishing rule.  ISA gives you an "target 
principle name is incorrect" in this case.  This is equivalent to the IE "The 
name on the security certificate is invalid or does not match the name of the 
site" error.  Change the data in the "server" field of the "To" tab in the web 
publishing rule to match the common name in the certificate.  If you use the 
same data in the "server field of the "To" tab of the web publishing rule as 
fond in the Exch cert common name, this error will cease.  This error will stop 
if the "server" field in the "To" tab of the web publishing rule matches the 
common name of the certificate installed on the Exchange server.

A3 - the certificate errors have *nothing* to do with the path portion of 
either the client request or the web publishing rule.  The path portion of the 
web publishing rule is not in any way affecting ISA serve's ability to acquire 
or evaluate the certificate offered by the Exch server.  The certificate 
offered by the Exch server has no relationship to the path data in the web 
publishing rule.  There are no errors related to the certificate offered by the 
web publishing rule and the path specified in the rule or requested by the 
client.  There is nothing you can do to solve the non-existent errors that have 
no relationship between these two things.

Go back and re-read the relevant sections in the book, articles and KBs related 
to certificates and ISA server.

Dynip.com will not allow me to obtain a Certificate from VeriSign or any other 
public, trusted CA and apply it to our DDNS name
(company.dynip.com)

If I have to get a certificate from VeriSign or any other public, trusted CA, I 
will have to get a static IP.

BTW, I'm just wondering why most of the help I get on this discussion list is 
so convoluted? When I ask a question, I never get a direct answer, it's always 
some obscure, sometimes pretentious, sarcastic statement.

I really appreciate the free advice given here by you highly trained experts on 
ISA, but for those of us who are rookies and are just trying to get ISA working 
like it should, those of use who do not have an IQ of 200, need something more. 
If someone asks, "How do you get such and such a function to work right?", 
someone should be able to say, "Do this, this, this, then that, then you should 
be fine." Or at least give a direct link to a tutorial, whitepaper, tech note, 
whatever. Instead of getting an answer like, "It's right there on the website."

This is what I need to know:
The certificate for my EXCHANGE box is installed on the ISA box - I exported it 
from the EXCHANGE box and imported it into ISA. Is this not good enough? All I 
want to know at this point is - can I use a certificate created by an internal 
network CA for RPC over HTTP from the outside world, or not. Do I have to have 
a 3rd party (ie: VeriSign) certificate to get RPC over HTTP working from the 
outside? If so, I will go get a static IP, get a registered domain name for 
that IP, get the certificate, and be done with it.

But since OWA works fine with a certificate issued on my internal network CA, 
why can't RPC over HTTP? I would like to know the WHY.

Thanx,

-TRogers

"Dynip.com will not allow certificates to be assigned to their customer DNS 
records"?!?

Can you clarify this?
Certificates are not assigned to DNS records at all.
Are you saying that they don't support redirection to HTTPS?

OWA is working fine - no issues at all.

The certificate for the EXCHANGE box is installed on the ISA box - I exported 
it from EXCHANGE and imported it into ISA. Is this not good enough?

And I was not recv'ing any error messages, not in the Event logs, not on the 
screen, etc. The ONLY error I recv'd was "Your Exchange Server is offline or 
not available." Not even any error messages in the Outlook Client Connections 
box. If I had error messages coming at me, I would be looking at the docs and 
KBs - no problem.

I'm not totally pathetic. ISA is the ONLY software I have had any trouble 
mastering. I have read TShinders books, MS TechNet, White Papers, etc and ISA 
know-how still eludes me for some reason.

So basically, in order to use RPC over HTTP from the outside I need to obtain a 
3rd party certificate from VeriSign or someone like that in order for this to 
work?

If that is the case, I will also have to get a static IP because Dynip.com will 
not allow certificates to be assigned to their customer DNS records.
