Question : OWA not working after Exchange 2007 SP1 failed

I tried to install Exchange 2007 SP1, but it failed due to a problem with the Hub Transport configuration, but after the failure it left the Exchange non working and although I have done a reboot there are still problems with the OWA not working and the following error sin the Event Log

Event ID: 2268
Source W3SVC-WP


Could not load all ISAPI filters for site/service. Therefore startup aborted.

and

Event ID: 2214
Source W3SVC-WP


The HTTP Filter DLL C:\Program Files\Microsoft\Exchange Server\ClientAccess\owa\auth\owaauth.dll failed to load. The data is the error.

When you try to access the OWA from outside the network, you get the following Error

Server Error in '/owa' Application.
________________________________________
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this
application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".




   
       
   


Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.




   
       
   


I can't believe a failed installation of a service pack can cause so much mayhem, please can someone help me get our OWA working again

Answer : OWA not working after Exchange 2007 SP1 failed

After speaking with MS, they told me to edit a few registry keys and to make some config changes to Exchange and to run SP1 again and all is now well, but thanks for trying to help.
