note 49053 added to install.windows.extensions

I am using php-4.3.4-installer package on windows XP with IIS 5.1 In past I enabled php_gd2.dll extension and its working fine. But now I enabled php_iconv.dll and copy this file into my extensions dir, then copy iconv.dll into my system dir but I am getting this error Unkown(): Unable to load dynamic library 'D:\php\extensions\php_iconv.dll' - The specified procedure could not be found.
