OWA all of a sudden stops working from outside

Hello,

I've had owa working fine for quite some time now. Using Exchange 2000
on Windows 2000 server. All of a sudden it seems to stop working from
outside. Using SSL, I get the security prompt, accept it and then just
a "page cannot be displayed" message. Everything works fine from inside.
From outside, I can get in with another browser like Mozilla firefox.
Is this an authentication issue?

Thanks,

Is this true for all external access? Have you tried using IE on another
outside computer?

i've seen this problem before, if your internal users are having the same
problem, check to see if the certificate has expired, if it hasen't restart
your iis service and see what happends.

Yes, this is true for all external access. IE on any other machine from
outside does the same. Everything works from inside.
Have verified nothing being blocked at firewall as well. We have a
Linux box acting as a front end that sits on the DMZ but nothing has
changed with this as well and the setup has worked flawlessly for about
a half a year.
The only thing I can think of is that shortly before this started
happening, the exchange server went down because of a power outage. The
UPS went dead as well, so the exchange server did not power down
gracefully. However, everything still seems fine, all services start
and OWA works just fine from the inside. Any idea's? We had someone
else from the outside come and look at it and it has him stumped as
well. I guess the thing that is so strange about it, is that other
browsers work from the outside. I tried it from Mozilla Firefox, and
also had another user try it from Netscape and they both worked.
Thanks

Everything works just fine from inside. I checked the certificate, and
it is not expired. Mozilla firefox and Netscape work from the outside,
but not IE. It has me stumped.
Thanks
