Hi Nick,
But the ISA firewall best practices analyzer and see what it has to say
about your certificates.

Subject: [isalist] Resolving external OWA access problem
http://www.ISAserver.org
Hi there everyone
Got a strange problem with OWA. First, my config :
Exchange 2003 SP2 on Windows 2003 SP1
ISA 2000 on Windows 2000 Server SP4
Now, my OWA had been working fine since I upgraded to Exchange
2003 sometime in late 2003. Then about a month ago, the certificate
that I used expired. I was getting a message whenever I tried to access
the site complaining about the certificate, so I went to the Exchange
server and renewed the certificate from there and then the problem went
away. It seemed strange that I didn't have to do anything on the ISA
server, but things worked fine so I didn't' worry about it. Then last
week the the whole thing stopped working. Now, I should say, I can
access the site fine internally. Its only when I try and access it
externally that things don't work. I don't even get the message about
an invalid certificate. I just get nothing. IE thinks for a while and
then just seems to go back to the page where you were, as if nothing had
happened. So, seeing as I needed to apply SP1 to Windows 2003 server
and SP2 to Exchange 2003 I went ahead and did that thinking it might
shake some things up and make things work. Well, no luck. So next, I
went to the Exchange server, and exported the renewed certifcate and
imported it into ISA server, since on the ISA server it showed it as
expired. That all seemed to work fine, but still no joy with the OWA
externally.
So, I'm stumped now and was hoping that somebody could point me
in the right direction as to where to start looking for some clues as to
whats wrong. I've looked in the event logs but I don't see anything
indicating any kind of error there. I'm not sure which logs to check to
see if the traffic is coming thru.
Any help would be greatly appreciated,
Thanks
Nick
