Problem with ingres extension for php

Hi,
I try to use the ingres extension for php (php_ingres.dll). I use php
5.1.1 (on iis win2000)which works fine without using the extension.
As soon as I put the line extension=php_ingres.dll to my php.ini I get
the following error when I restart iis:
Unable to load dynamic library 'c:\php\ext\php_ingres.dll' - The
specified module could not be found.

The extension_dir in the php.ini is: extension_dir = "c:\php\ext" and
php_ingres.dll exists in that directory. I downloaded php_ingres.dll
from http://pecl4win.php.net/ext.php/php_ingres.dll (the 5.1.1.
version).

Does anyone have an idea how to solve this problem?

Thanks.

Stefan.

If you do not have Ingres installed you will see this message. Or rather
if php_ingres.dll cannot find iilibapi.lib this will happen.
What version of Ingres do you have installed? How do you have IIS
configured. Can you send me, offline, the output from phpinfo().
