include woes

Hi All For some reason wer'e trying to set up php4 running on IIS3. Install and configuration went ok until I try to include files. If I call an include in index.php, if I go to the directory ie. /temp/ it will include the file. But if I call the file directly. ie /temp/index.php I get a CGI error. and no error log (typical) I've tried setting include_path in php.ini to . ./ with quotes and without I've tried using include"./include.php"; include "include.php" with no success Can anyone shed some light on this or do I have bin it and install Apache??
