Specify php.ini location in windows

Hi, I am having a small problem with PHP/Windows. [config] Windows 2000 Server IIS 5 PHP 4.0.6 I have a server with a php.ini in the c:\winnt directory and a site running fine with that configuration. I need to set up a new site, using a different php.ini. The new site is set up in IIS but I cannot find a way to make PHP look to a different php.ini other than the one in c:\winnt. I have tried using the -c command line option in the app mappings section but to no avail. Here is what I have in the executable text box: C:\Inetpub\php\php.exe -c z:\Dir\With\Other\IniFile %s %s PHP pages execute fine but a page with phpinfo() shows that php is still reading the file from c:\winnt\php.ini Any ideas? Thanks in advance, Patrick.
