I upgrade Exchane 2007 to SP3 and it went without errors.
However on using OWA I get an error.

https://mailserver.domain.co.uk/owa/auth/owaauth.dll

The custom error module does not recognize this error.

This error appears regardless of a correct username/password combination.

OWAApppool show net 2.0.50727.
owaauth.dll version is 8.3.83.0

Any help appreciated

Thank you

Did you install the latest rollup after installing the service pack?
If not, go and do that to begin with.

No, wanted to make sure everything worked before I went ahead and did anything else.

I would patch it to begin with. SP3 on its own is very old. Bring the server fully up to date.

Have you seen this TechNet forum thread?

Don't want to go over old ground if you have.

Is there anything else on the server that could have changed the netframework configuration?

There's nothing thats changed other than the SP£ upgrade and rollup.

I saw that link but the instructions aren't clear.
I found the same problems as the OP.
Menu options suggested weren't listed etc.

However if I select basic settings for the web site the pysical path is correct
There is a button to test settings

Which throws an error

The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that <domain>\<computer_name>$ has Read access to the physical path. Then test these settings again.

C:\Program Files\Microsoft\Exchange Server\ClientAccess\OWA has read access for authenticated users, and full permissions for system and administrators

Checking the logs I get an error

The Module DLL C:\Program Files\Microsoft\Exchange Server\ClientAccess\Owa\auth\exppw.dll failed to load.  The data is the error.

About to follow steps i nthis article

In the particular case of owaauth.dll failing to load, you need to do the same thing with the permissions of the folder '%Program Files%\Microsoft\Exchange Server\ClientAccess\Owa\auth'.

That was the issue.
Once I'd correctly added the traverse folders/execute files permission it worked like normal.

Odd bcasue the permissions are inherited and so I had to explcitly set them.
