HTTPS not working for OWA/Exchange 2007

Last week I had OWA and Exchange fully set up. I could access it via https://mail.alden-hebron.org/owa (please dont laugh if you get to it - I need to buy a security certificate) Anyways sometime over the weekend something happened and now we can't get to it externally. Nothing was really changed in the firewall except one small port 80 setting but it had nothing to do with port 80 for the wan to the lan ip of the exchange server. What else could cause this? Thanks!

RIght, that's what I thought that you meant.  However since I can get to it from outside I would suspect that it could be a routing issue.  Are you using any kind of hosts file?

Https does not work - what is the error you get - could you please post that.
Also, what is the result if you try to open the same link on the Exchange server - CAS server ?
Is SSL Enabled on the OWA Virtual Directory with port 443 specified ?
Any errors specified in app logs related to OWA ??
Do you have any other subject alternate name specified ?

The link comes up fine for me, but with a certificate error.  As you mentioned, you were looking at buying a certificate already so that issue looks like it's taken care of.  

Some obvious things to check would be your IP address --> did it change, and possibly your DNS & PTR records with your ISP / host?

The error that comes up for me is Page can not be displayed. I am getting it while i am within the same LAN as that page - could that be the problem?

Thanks

What do you get when you try it from a WAN or remote site?  If it isn't coming up internally then it could be a routing \ dns \ firewall issue.

I meant while I am on the same lan as that computer. Obviously we are using a local address to resolve it from within but I was just testing it...

What is the address of the page that you're trying to access?  My OWA address is https://servername/exchange.  You may want to check your router or firewall for an entries that are blocking local access to your port 443.

You were on the right track and closest of all the others. It was a routing issue. My Firewall needed to allow routing from LAN devices to Other Lan Devices in the 443 port range.
