4.3 The specified module could not be found.

I have been keeping our PHP version up to date for several years now. The only extra extension we load is php_ldap.dll. I extracted and installed PHP 4.3 exactly the same way I always have and for some reason it refuses to find any of the extensions. With 4.3 I always get: Content-type: text/html X-Powered-By: PHP/4.3.0 PHP Warning: Unknown(): Unable to load dynamic library 'C:\Program Files\PHP\extensions\php_ldap.dll' - The specified module could not be found. in Unknown on line 0 ---------------------- That file does exist, I've tried changing the extension directory to one with no spaces and putting the file there, it didn't work either. Any ideas? Thanks. <>< Ryan
