OWA and OMA Failure - Exchange 2003 Enterprise

Exchange 2003 Enterprise (Backend) Service Pack 1, One Exchange server only.

OWA has completely failed, error message is "Page Cannot be Displayed - HTTP 500 Internal Server Error", this also applies to OMA.

Apart from OMA and OWA Exchange is working fine, no modifications to the server have taken place.

I would be very grateful if anyone can shed some light on the situation, I am fairly new to Exchange, so please take it easy.

While that would appear to resolve the problem, those authentication settings are actually incorrect.
On a correctly working Exchange server the authentication settings on /exchweb should be anonymous only - no other authentication settings should be applied.

If you made those changes and it started to work then that would indicate the problem is with authentication. I would probably suspect the anonymous user account.

Any reason why the server hasn't been taken up to Exchange 2003 SP2?
That would be the first thing I would suggest as it will probably reset the OWA folders to their correct settings.

Hi Simon

I have been using Microsoft Baseline Security Analyzer 2.0 and Best Practices Analyzer Tool to keep the server updated, perhaps it would be a good idea then to update to service pack 2, is there anything I should watch out for with SP2?

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Do you have the original release of intelligent message filter (IMF) installed? If so, it needs to be removed as that is now built in Exchange.
Otherwise read the readme file that comes with the service pack - it covers any major issues. However the service pack is rock solid and shouldn't cause too many problems.

Hi Simon

I have installed service pk 2, it has improved the situation some what, I can now use OMA.  OWA now loads but with errors on the page, I have sent you an e-mail with a print screen, I hope you don't mind.

Check the authentication settings on the Exchange virtual folders in IIS Manager:

/exchange - integrated and basic only
/exchweb - anonymous only
/exadmin - integrated only
/public - integrated and basic only.

Hi Simon

Just checked out the settings, all are as you listed.

Do make sure that you have flushed out temp internet files before trying again.

Check the application pool settings as well.

/exchange - ExchangeApplicationPool*
/exchweb - ExchangeApplicationPool*
/exadmin - ExchangeApplicationPool*
/public  - ExchangeApplicationPool*
/oma - ExchangeMobileBrowseApplicationPool
/Microsoft-Server-ActiveSync - ExchangeApplicationPool

* will probably show ExchangeApplicationPool but greyed out.

Hi Simon

/exchange - ExchangeApplicationPool* Greyed Out
/exchweb - ExchangeApplicationPool* Greyed Out
/exadmin - ExchangeApplicationPool* Greyed Out
/public  - ExchangeApplicationPool* Greyed Out

/oma - ExchangeMobileBrowseApplicationPool* Execute Permissions = Scripts Only, Application Pool = ExchangeMobileBrowseApplicationPool

/Microsoft-Server-ActiveSync - ExchangeApplicationPool* Execute Permissions = Scripts and Executables, Application Pool = ExchangeApplicationPool
