"No Input File Specified"

Greetings All, I'm trying to install PHP5 using the ISAPI (php5isapi.dll) file rather than other options onto Windows Server 2003. I've unzipped PHP to c:\PHP and setup php.ini, added it to the PATH and moved it to C:\Windows (just in case). I copied the .dll to the system folder and set up IIS6 to use both the .dll first in the C:\PHP folder and then in the system folder (in case that was the problem). Now, I don't know what to do. I've tried erasing the whole thing and starting over but that didn't help at all. Has anyone fixed this problem?
