TYPO3 on IIS 7.5 - HTTP 500

Question

I have a virtual server with Windows Server 2008 R2/IIS 7.5.

I set up PHP 5.2 with FastCGI, MySQL 5 and put TYPO3 on it. Which doesn't work. I just get an "Internal Server Error - 500", which pretty much sums it up. No additional information.

PhpMyAdmin is working flawlessly, I imported the database with it (migrating a locally developed installation to this server).

Any hints or ideas?

IIS7 defaults to hiding detailed error messages. Add this to a file called web.config in the root of your site:

<configuration>
  <system.webServer>
    <httpErrors errorMode="Detailed" existingResponse="PassThrough" />
  </system.webServer>
</configuration>

That should force IIS to render the underlying error.
