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 an error in 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.

Can someone help me get our OWA working again

Hi,
I had a similar problem after a failed upgrade. My advice is to fix whatever the Hub Transport configuration problem was and continue with the upgrade. Once the SP1 upgrade is successful, OWA should work.

What was the specific error you were experiencing? Maybe I or the forum can help.

The reason the install failed was because it was expecting a different FQDN, so I have now fixed this, but in following various advice trying to fix the OWA problem I now have a bigger problem in the I have uninstalled the CAS, but cannot install again because it thinks the OAB Server has been deleted, which of course it hasn't and I am getting an error message about RPC Errors.

Do you think that trying to install SP1 will resolve the CAS problem.

Not sure to be honest, but I would. Before doing so however, if you run the exchange analyzer tool does it identify and come up with a resolution for the OAB?
