When attempting to browse to OWA, we get this: HTTP/1.1 503 Service Unavailable
Exchange 2003 running on Windows Server 2003
No errors or problems in the server event log.
This is a confusing one. I've tried the KB article that has you recreate the IIS virtual directories - twice. Then reinstalled Exchange.
Note: everything was fine util I changed the default port in IIS from 81 to 80 (trying to get OMA working). Now OWA is down also - otherwise Exchange seems to be okay.
Thanks in advance...
