win32 php on win2000 does not seem to be searching its own C:\php\dlls folder???

Hi, Im using php 4.3.3 on win 2000 server, and ive enabled extensions like so; extension=php_gd2.dll extension=php_gettext.dll and set the extension_dir to C:\php\extensions and php loads the gd2 library ok, it just fails to open the gettext dll. with a "PHP Warning: Unknown(): Unable to load dynamic library 'C:\php\extensions\php_gettext.dll' - The specified module could not be found. in Unknown on line 0 " error its definitely there, and its permissions are ok. so I run filemon to watch what files it opening, and its looking for libintl-1.dll and a load of others from the C:\php\dlls folder, but from the filemon output, php.exe is not even looking in that folder, I can add it to the path, but it seems like a bit of a hack to fix something thats probably should be set elsewhere/ Anyone got any ideas what I have missed; Cheers T.
