Access IIS 7.5 HTTPS Default Web Site from network failed

I have a Default Web Site on Windows Server 2008 R2 and I have installed a SSL certificate underServer Certificate for the server.

And then I have added a new HTTPS (443) binding in the Edit Bindings on the Default Web Site .

Next,  I clicked SSL Settings in the Default Web Site home page and selectRequire SSL checkbox and click Apply.

Assuming the web server name is www.mywebserver.com. 

I can access the https://locahost/ or https://www.mywebserver.com/ on the server itself. I do not have any problem.

However, if I try to browse the https://www.mywebserver.com/ on my desktop PC, I received a page "Internet Explorer cannot display the webpage" while I can run "telnet www.mycompany.com 443" in command prompt and my session is connected.

If I remove the HTTPS binding in the Edit Bindings and clear the Require SSL, I can browse the http://www.mywebserver.com on my desktop PC.

How can I fix this problem?

Thanks,
