Php.exe doesn't read php.ini (Php4)

Hello, This is my configuration: Windows NT 4.0 + SP 5 + IIS 4.0 + Php 4 (cgi mode) php 4 resides in directory d:\php4, all files included ini and dll's Path env. variable is set to PATH = ...;d:\php4 THE problem I have a php file with this line <? phpinfo(); ?>. When I load the file the resulting page shows get doc_root = "no value", local and master value. My question is how to get php.exe to read my php.ini file. One thing to notice is that same file executed from command line (php -f info.php > info.html) shows doc_root = "d:\phpdocs", local and master value, which is correct. Any idea???
