Need help with OWA on SBS 2003

Need a little help getting OWA and email on cell phones working...

We have a Windows SBS 2003 Server running Exchange 2003 SP2.  OWA is working internally via http://serverIP/exchange, httpS://serverIP/exchange and http://servername/exchange.

Internally, when we go to httpS://servername/exchange - we get the "uses an invalid security certificate" in Firefox and "There is a problem with this website's security certificate" in IE.  We add the Certificate exception and can get in.

Externally, when we go to httpS://external-IP/exchange, we get the same Certificate error, but when we add the exception in IE or Firefox, the screen sits there blank and never prompts us for OWA login credentials.

We have https (not http) forwarded in the Firewall to the SBS server.

We have our email filtered through a Barracuda Spam Firewall at a different location if that makes any difference.

Any ideas?

Same thing...

Firefox sits at a blank white screen, IE says "Internet Explorer cannot display the webpage"

check iis on the owa server to see if you are redirecting anything and if your redirects are pointing to internal server names that external users can't access. maybe open 80 through the firewall for a few minutes to test if the firewall is the problem (but i doubt it)

I forgot to mention:

This was working about 2 weeks ago.  Exchange was running on a different 2003 Server - not on the SBS box.  The outgoing IT support had to remove that Server, so they migrated the mailboxes to the SBS Server and Exchange was configured to work there.

External OWA and email on Blackberries etc. have not worked since.

Would adding a trusted certificate help this?

No, it's not a cert issue.

You need to do the following - I've only come across this once before, and this fixed it...

Uninstall IIS completely
Reinstall IIS
Reregister OWA in IIS
This may help :-

Are you sure?  The Server was installed in January.

The certificate was created on 3/31/09 (the day before we took over) and is for servername.domain.local.  The status is "This CA Root certificate is not trusted because it is not in the Trusted Root Certification Authorities store."

This is what IE says:

There is a problem with this website's security certificate.
The security certificate presented by this website was not issued by a trusted certificate authority.
The security certificate presented by this website was issued for a different website's address.
Security certificate problems may indicate an attempt to fool you or intercept any data you send to the server.

Certificate Services was not installed.  I am in the process of creating a new cert.
