Question : Cannot access OWA when SSL is installed

When SSL is turned off I can access OWA via http:// internally and externally but when I enable SSL we get page can not be displayed with no error messages.  Once SSL is enabled and I try to access via http:// I get a page that states that the site requires secure access, HTTP Error 403.4.

The environment is a single Windows 2003 Standard server acting as a DC, Exchange server and terminal server.  We have a Netopia 3347 router with ports 80, 25, 3389, 443 and 143 open and pointed to the server.  Exchange 2003 has SP2 installed.

I installed certificate services as an enterprise CA, generated a certificate request in IIS under the default web site, used the server.domain.com as the common name, saved the request, accepted it thru the internal certificate website, and generated a base 64 encoded certificate and then appended the certificate to the default website.  I checked the Require SSL channel and require 128 but encryption, allowed anonymous access and granted all IP access.

What did I miss?

Answer : Cannot access OWA when SSL is installed

Ignore the require SSL setting. If you have a certificate in place then you should be able to use HTTP and HTTPS interchangeably.
If nothing loads when you use HTTPS, but the same URL works with HTTP, then the secure session isn't being established. That points to a bad certificate.

You could use the selfSSL tool within the IIS Resource Kit to create a self generated certificate for testing purposes, but I wouldn't recommend its use in production. Telling users to ignore certificate warnings is a bad idea.
