SSL - Internet Explorer cannot display the webpage

I am here out of sheer desperation...
My company has a web site that has been running for years without SSL enabled. They have had a certificate installed since day one, but no one ever enabled SSL in IIS...
This is where our problem begins.
We have updraded the site with new enhanced features and from ASP to ASP.net.
When we discovered that SSL had never been enabled on IIS we all went "Ok, that cool, we can just enable it and then use https instead of http". Yeah right!!!
We have the new .net version of the site in a virtual directory off the main site running on what I think is IIS 5, but it could be 6, (how do I check the version of IIS) but I don't think that the version of IIS is the problem here.
The problem we are having is as follows...
I enable SSL on IIS on the main site.
If I use http to browse to the site, I get the propper response telling me that the site is a secure site and I have to use https. So far so good.
If I then use https to browse to the site I get the generic "Internet Explorer cannot display the webpage" message, with a whole bunch of other rubbish that is of no use...
Most likely causes:
You are not connected to the Internet.
The website is encountering problems.
There might be a typing error in the address.
What you can try:
Diagnose Connection Problems
This problem can be caused by a variety of issues, including:
Internet connectivity has been lost.
The website is temporarily unavailable.
The Domain Name Server (DNS) is not reachable.
The Domain Name Server (DNS) does not have a listing for the website's domain.
If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section.
For offline users
You can still view subscribed feeds and some recently viewed webpages.
To view subscribed feeds
Click the Favorites Center button , click Feeds, and then click the feed you want to view.
To view recently visited webpages (might not work on all pages)
Click Tools , and then click Work Offline.
Click the Favorites Center button , click History, and then click the page you want to view.
This is where I am at a complete loss for how to continue.
I have googled the message "Internet Explorer cannot display the webpage" and only got stuff telling me to enable SSL on my browser and references to sites telling me how to implement SSL.
None of these helped.
Please let me know if you have had a similar problem and if you have resolved it, how you did it.
Thanks in advance

Nothing helped? what about the following ?
PRB: Error "Page Cannot Be Displayed" When You Connect Through HTTPS
HOW TO: Determine If SSL Connectivity Is Not Working on the Web Server or on
an Intermediate Device
"Cannot find server" or "DNS" Errors When Using SSL (Q & A)
at command prompt, enter
"netstat -an", see anything binding on port 443 ?
anything in event log ?

This link did it for me... sort of...
I have a very anoying problem that has just come to light since SSL has started to work...
We connect to the web server through an intranet, and when we surf to our site using https through this intranet it works without any problems.
However, no one outside of our domain can navigate to the site using https???
This seems strange to me, but maybe we are doing something wrong?

Well, is there any fireall in between ? does incoming port 443 traffic able to reach your internal IIS ? or port forwarding / NAT setup correctly?
