title: Adding extensions for MS SQL Server to PHP 5.3.9 ini file causes FastCGI Error on server
body: <p>I am attempting to get a drupal site to work with SQL Server. I have followed the instructions outlined <a href="http://learn.iis.net/page.aspx/246/using-fastcgi-to-host-php-applications-on-iis/" rel="nofollow noreferrer">here</a> to get PHP working. Then I downloaded the drivers <a href="http://www.microsoft.com/download/en/details.aspx?id=20098" rel="nofollow noreferrer">here</a> and unpacked them to my PHP/ext folder.  I then wrote an awesome php test page consisting of the following piece of code.</p>
  <pre><code>&lt;?php phpinfo(); ?&gt;
  </code></pre>
  <p>opened up a web browser and pointed to the file localhost/phpinfo.php. All works wonderfully.</p>
  <p>I then opened upt the installed .chm file that came with the php drivers for sql server and made the appropriate changes.</p>
  <p>Based on the following from my PHPInfo page:</p>
  <blockquote>
  <p>PHP Extension Build   API20090626,TS,VC9</p>
  </blockquote>
  <p>I added the following lines of code to my php.ini file</p>
  <pre><code>[PHP_PDO_SQLSRV_53_NTS_VC9]
  extension=php_pdo_sqlsrv_53_ts_vc9.dll
  [PHP_SQLSRV_53_NTS_VC9]
  extension=php_sqlsrv_53_ts_vc9.dll
  </code></pre>
  <p>I then restart IIS and point back to my awesome phpinfo.php file and get the following:
  HTTP Error 500.0 - Internal Server Error
  C:\Program Files (x86)\PHP\php-cgi.exe - The FastCGI process exited unexpectedly</p>
  <p>with some lightweight recommended information on suggested things to look at for resolution.  e.g. file access, folder access.<br />
  There is no rights issue IIS_IUSRS has execute rights on the PHP/ext folder.</p>
  <p>Anyone with ideas on how to resolve this?  Am I missing something somewhere to make this work?</p>
