I setup an SBS premium edition server w/ ISA a few days ago. Everything was running fine including OWA, active sync etc until today when something when wrong. I've been able to bring it back to almost normal but I cannot get OWA up an running, every time I try to login to OWA the application log registeres the following event:
Event Type: Warning
Event Source: Microsoft ISA Server Web Proxy
Event Category: None
Event ID: 14148
Time: 11:38:29 PM
The Web Proxy filter failed to bind its socket to 188.8.131.52 port 443. This may have been caused by another service that is already using the same port or by a network adapter that is not functional. To resolve this issue, restart the Microsoft Firewall service. The error code specified in the data area of the event properties indicates the cause of the failure.
I used nbtstat to check what service is using 443 and it is IIS so I removed port 443 from the site... still the same problem & OWA won't even come up internally. I following the instructions on this page to the letter: http://www.isaserver.org/articles/2004pubowartm.html
does anyone have any thoughts?
