[PHP/IIS FastCGI]: Error after installing FastCGI and PHP 5.3.0 nts on windows

I am getting following errors when I try to execute any PHP application after I installed IIS FastCGI and PHP 5.3.0 non-thread-safe on Windows XP:

PHP Warning:  PHP Startup: Unable to
load dynamic library 'C:\Program
Files\PHP\ext\php_enchant.dll' - The

How to get rid of this?

1. Check that the offending dlls actually are there in the ext folder
2. Check that in your php.ini the extension_dir value is enclosed by quotes
3. Finally, check the documentation of those extensions for additional dependencies (e.g. I recall the Oracle extensions requiring some dlls that come with the Oracle client...)
