Setting up PHP

Hello, I have installed PHP this afternoon. I download the most recent Windows version available today from www.php.net. I have installed it on a Win2K Adv Server running IIS 5.0. I have prepared a test page (test.php)and placed it in the wwwroot directory on the web server. When I try to access the test page on the web server (either from the server or remote machines) I get the following error: CGI Error The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did not return are: Then nothing. I am just beginning to learn PHP and would like any assistance that anyone could provide to get past this error. Thanks, Lee Jordan
