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
Date:            11/30/2006
Time:            11:38:29 PM
User:            N/A
Computer:      TITAN
Description:
The Web Proxy filter failed to bind its socket to 67.52.187.67 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?

Have you rerun the Configure Email & Internet Wizard?
The reason the bind will fail is that you will have had two services trying to run port 443 services on the box against the same IP address.
If you have removed port 443, you will likely have caused issues with your companyweb also. Whilst internally you connect to it on port 80, it is shared out to the Internet over port 443.

If you have configured these things manually then you could be into a world of trouble here as the wizards are all provided to make sure the services all interact correctly, control the appropriate group policies and put the users/computers etc into the correct OU's.

this often happens on SBS installs after the first reboot. Sorry if this is not the case for you but many people are not aware of the way to install SBS, as you probably know it is vastly different from a normal Windows 2000/2003 installation. Even adding work stations etc must be done through the browser, not through Active Directory for example.

Anyway, blog finished. When you say you have got most of it back together, how did you do that? Manual configurations?

Thanks Keith, I plan to take some time today to do this.  Will start from scratch & use the wizards.  My problem is that I'm using multiple public IP addresses which the wizards don't really address but I guess the thing to do is run the wizard and the adjust the details manually from ISA.  thanks & will keep you posted.
