Hi Alap,

That doesn't help me. If you're trying to use security through
obscurity, then you'll get that at the expense of a definitive answer.
But without the exact details, I won't be able to solve the problem.
Maybe somebody else will be able to.

I have published OWA site using New Web Publishing Rule wizard.  In the
rule wizard I ticked the options Redirect the request to this internal
web server (Typed the FQDN of our Exchange server) and Send the original
host header to the publishing server instead of the actual one.

The FQDN of our Exchange server (OWA Server) is different to the domain
name that the external clients connect to.

Hope this helps.

Hi Tom,

I am testing it from external clients.

Hi Alap,

What are the exact details of your Web Publishing Rule?

Are you testing from EXTERNAL clients?

Thanks!

http://www.ISAserver.org

I am currently experiencing problems with configuring Outlook Web Access
using Exchange 2K and ISA2K.  I have a domain name pointing to the IP
Address of the external ISA interface.  Our ISP has created A Host
record for this domain.  I have followed the article
http://www.isaserver.org/tutorials/Publishing_Exchange_2000_Outlook_Web_
Access_with_ISA_Server.html

and created a destination set based on the publicaly available domain. 
Also I have published OWA site using New Web Publishing Rule wizard.  In
the rule wizard I ticked the options Reditect the request to this
internal web server (Typed the FQDN of our Exchange server) and Send the
original host header to the publishing server instead of the actual one.

The Exchange Server is SecureNAT client and it has internal DNS entries.

When I connect to this OWA site it comes up with an error "Cannot
connect to the server or DNS error".  I don't know where I am going
wrong.  When I ping my publicly domain name and it does bring up the
response with the IP Address of our External ISA interface.

Don't know what I am doing wrong.  Please help.

Pre-shared Key

http://www.ISAserver.org

Hi Roy,

I thought it was Shinder-san? I get confused about those things :)

Anyhow, are you trying to implement an L2TP/IPSec site to site VPN using
a pre-shared key or computer certificates? You can't do both. So, if you
want to use a pre-shared key, don't install computer certs. If you want
to use computer certificates, then don't configure a pre-shared key on
the VPN gateway endpoints.

HTH,
