Hi, i have recently attempted to setup PHP with IISv6.0 and have run into some problems after installation. Basically, no PHP code seems to work. I'm fairly new to PHP but do have some understanding of how it works. Here is my setup and what i have done. Whenever i try to run any PHP, even the most basic script such as hello world fails with this error message; [CGI Error, The specified CGI application misbehaved by not returning a complete set of HTTP headers.] My software / hardware ------------------------------- PHP (Manual Installation) 5.2.5 zip package Windows server 2003 R2, SP2 IIS 6.0 AMD Athlon 64 X2 Dual Firefox & Internet Explorer php-recommended.ini (renamed of course) My installation ------------ Files have been placed in C:\PHP PATH has been modified to include c:\PHP NTFS security on c:\PHP is EVERYONE = FULL CONTROL, nothing else IIS root is located at c:\inetpub\wwwroot Web Service Extensions include c:\PHP\php-cgi.exe [ALLOWED] Under the default website under home directory tab 1. Read access, log visits, index this resource 2. Execute permissions = scripts only 3. Configuration... Application extentions contain c:\PHP\php-cgi.exe (.php) [ALL VERBS] PHP.ini doc_root = "c:\inetpub\wwwroot" extension_dir = "c:\PHP\ext" cgi.rfc2616_headers = 1 I have also tried accessing the pages through these 2 methods //computer/folder/index.php http://localhost/folder/index.php This is an example of code that is failing. It doesnt get any more basic than this... <?php Print "Hello, World!"; ?> I'm not really sure what to do from here, searching for the error message on google has given me absolutely nothing and i've tried to follow the install.txt manual to the letter. Pulling my hair out - any help would be greatly appreciated!!
