IIS wont start with PHP4

I've installed PHP4b4pl1 on WinNT with IIS. IIS will not start as long as I have the php.ini file in the windows directory. If I rename the php.ini file, IIS will start. Then I can rename the file back to php.ini and it works, sort of. At that point, I am having problems with a module. If the php.ini file is not in the windows directory when IIS starts, will the modules that I've specified in php.ini be loaded? Is phplib supported under php4? Are the modules that I am using with php3 supported under php4? Anyone had similar problems? Thanks. Fred K Gohsman Ketl Internet Consulting http://www.KETL.com
