Exchange 2003 OWA stopped working externally

We have a SBS 2003 server.  For years we have been using OWA with self signed certificate. To login to OWA we used to use https://xxx.xxx.xxx.xxx/exchange.   I recently (few weeks ago) I installed a SSL certficate and everything was working fine until the server was rebooted yesterday.  There was some updates applied during reboot.  FYI.  After I configured SSL, I did not reboot the server.  This was the first time server rebooted since SSL change.   Now we can not access OWA externally.  I checked internally and use http://servername/exchange and that logs me directly into OWA mailbox of current user logged in.  For example, if I use http;//username/exchange on a user workstation, it will log me directly into that user without a login prompt like we were used to seeing.  So what I am really concerned about is the external link to OWA not working. Can anyone shed some light on my issue?  I will provide more info as needed.  Thank you.

I port forwarded 443 to server IP.  No ISA on SBS.  Error I receive is "The page cannot be found"  HTTP Error 404 - File or directory not found.

I tried using IP address and get same exact error message.  I just double checked firewall settings and they are correct.

Can you verify your public IP and then verify external URL IP?

Hi Spartan:

What do you mean?  Our public IP has not changed and external URL IP is https://remote.domain.com.  An A record is setup pointing to server public IP.

Did you have any redirects setup? Can you look at your firewall/router and verify that the traffic is being properly routed to the server?

If I use external https://remote.domain.com  without /exchange in url; it brings me to our old hosted website on our sbs server.  If I use /exchange I get the error mentioned.  Also I can see the certificate I setup when accessing either urls

Problem solved.  When I setup ssl; I created a website in iis with same name as external url.  This caused a dns issue after server was rebooted
