HTTP 404 – fife not found when accessing OWA

One of my clients is running Exchange 2003 with SP2. When trying to access the OWA, they receive HTTP 404 – file not found. I have searched Google to find the solution, but can’t fix it. Following MS article Troubleshooting Outlook Web Access, I created a test Virtual Directory called OWA. It works and shows text only format (see below) like OMA if the Application Pool is DefaultAppPool.

However, if I switch to the ExchangeApplicationPool, the test OWA will receive HTTP 404 too. Then I created a test pool call ExchApplPool and assign it to the OWA test, but that doesn’t fix the problem. The identity of ExchangeApplicationPool and ExchApplPool is Local System. Any suggestions?

Reset the virtual directories to start with .

That resolves many of the problems.

Thank you. That sounds like the solution. However, after following the instruction to re-set IIS, I still get the same error. I think it is some things to go with ExchangeApplicationPool.

Try recreating the application pool then.
