Can only see OWA from outside firewall on one Exchange 2003 in site
I've brought up a second Exchange 2003 server in my organization. The old
one allowed OWA access through the firewall. It's still online and
operational.
The new server won't allow access through the firewall. I can access either
from within my DMZ or from within my trusted side, but can only see OWA on
the old one from outside the firewall. For reasons I haven't had time yet
to address, we're not using SSL (that will change soon, but I'm up to my
eyeballs fixing long-standing problems now that my old boss left).
The final thing here is that until Wednesday, the new server WAS allowing
OWA access. Wednesday morning, it stopped...
I spent all day comparing configs on both. By late evening, I gave up and
went to bed. When I woke up the next day, OWA was open again!?!?!
All was well yesterday (Thurs) and then this morning, OWA stopped again.
Both mornings, it stopped around 7:30am - 8:00am. Not that I'm sure that
that matters - I'm trying not be get superstitious about this.
Anyway, there's nothing in my event log that points to anything happening
when OWA became inaccessible. I'm really at a loss and not sure where to
look?
Suggestions are VERY welcome at this point :-)
Thanks,
Mark

If you get to the server from within the network, then this isnt an
Exchange issue. I would check the firewall logs.

A curious thing I've just discovered today is that I can access OWA on this
one particular server - intermittently. For example, right after some sort
of reconfiguration or reboot. I updated my NIC drivers, which didn't
require a reboot when finished, and was able to access OWA, but my Windows
Mobile 6 device said that there was an error synchronizing. After several
minutes had passed, OWA no longer opened.
I messed around some more and made a change to my NIC that required a reboot
and after that reboot, OWA was again fully available for about five minutes,
then stopped. My mobile device still wouldn't synch.
How's that for a brain teaser? :-)
I'm banging my head on this - and it's Saturday - that's not fair!!!
Thanks,
Mark

Is the OS Windows 2003 SP2? It could possibly a SNP issue:

Have you run ExBpa against the server?
