Default web site error "Service Unavailable" for OWA works

We have a Windows 2K3 server running Exchange. When going to the default web
page, a browser gets a reaspons "Service Unavailable." However, the OWA site
(off the default web page) works. I had a redirection in the default web
page, which has worked for a couple of years, but a few months ago everything
directly in the default site has stopped working. This server is a DC.

I've gone through the various posts. One reference ADFS, which isn't
installed. Another posts referenced
http://support.microsoft.com/Default.aspx?id=842493, which I followed but to
no success.

Thanks for any guidance.

Re: Default web site error "Service Unavailable" for OWA works

Service Unavailable is a generic error message probably coming from http.sys
indicating that the website requested is not available. OWA (from memory)
runs in a separate web application pool, so that's why it's probably not
affected.

Please look in:
a) The Windows Event Log
and
b) the httperr.log file (in c:\windows\system32\logfiles\httperr)
and post any relevant error messages that you see in those two logs.

Thanks

Cheers

Re: Default web site error "Service Unavailable" for OWA works

There are two events in the event viewer, and I've tried several fixes on
Google to date.

Event ID: 2268, Could not load all ISAPI filters for site/service.
Therefore startup aborted.

Event ID: 2214, The HTTP Filter DLL \\?\C:\IISDebugTools\IISCHAgent.dll
failed to load. The data is the error.

Regarding the httperr file, here is what is in this since a reboot this
evening:

I went into Internet Services Manager and saw the DefaultAppPool had
terminated to an unspecified error. I right clicked and started it up, and
now the default web site appears. It errors out on a reboot, though.

I also noticed that an IISCrashHangAgent errors out as well.

Re: Default web site error "Service Unavailable" for OWA works

For each of the two events that you are seeing in the Event Log, please open
the event. There is a "copy" button (it looks like two pieces of paper).
Please press that, and past the entire event details here. Informtion such
as "the data is the error" is helpful information (it is usually a hResult
that can help tell us whu the filter failred to load).

The second thing to check is what ISAPI filters you do have configured for
the default web site.

Cheers

Re: Default web site error "Service Unavailable" for OWA works

Just for grins (I wish I had a better reason) I elected to remove
IISCrashHangAgent from the IIS configuration, and everything works fine. I've
rebooted, and the default web site comes right up. The errors are gone from
the event viewer and the httperr file as well.

Thank you.

Re: Default web site error "Service Unavailable" for OWA works

I did copy the entire error messages with the exception of "For more
information, see Help and Support Center at
http://go.microsoft.com/fwlink/events.asp." The second message did say "The
data is the error."

There are no ISAPI filters defined for the default web site.

Re: Default web site error "Service Unavailable" for OWA works

Hi,

When a message says that "the data is the error" there is usually some
infomation in the box towards the bottom of the dialogue box. This is
usually a hResult, eg 08 00 40 50

When you copy the information, the data you end up with looks like (notice
the data at the bottom):

Event Type: Information
Event Source: MSSQLSERVER
Event Category: (2)
Event ID: 9688

Re: Default web site error "Service Unavailable" for OWA works

The better reason would be that you are troubleshooting based on facts
instead of just guessing. :-)

The event log entry says that IIS failed to load an ISAPI Filter and
thus failed startup of the website with a 503 AppPool Offline, which
correlates with the results from httperr.log -- thus the correct
action is to remove the IISCrashHangAgent ISAPI Filter from IIS,
restart IIS, and it should correct the event log entry and the 503.
