IIS PHP 4.0 Problem

Sir, I am using PHP Version 4.0.3pl1 on Windows NT 4.0 SP 6a running Internet Information Server 4.0. Php (ISAPI version) is giving so much trouble that I am not able to run PHP files Properly. Whenever I run a php file sometimes IIS serves file properly but sometimes it just crashes and CPU load goes to 100% and everything starts running slowly. I have to restart the computer. When it serves php file properly and then I try to run an ASP file then it does not serves asp file and produces "page cannot be displyed" (Internal server error 500) or just stops waiting for file to download as if it was downloading the file from internet and then after 5-6 minutes "The page cannot be displayed (internal server error HTTP 500)" is displayed. And then php files also start producing (internal server error HTTP 500) erros. I have tried it on 3 - 4 computers and on every computer it does the same thing. I phpisapi.dll files when loaded into memory conflicts with ASP.dll and IIS is not able to serve asp files. When I want to run asp files I have to remove then PHP filter from the ISAPI filters option of IIS and restart the computer then only IIS starts serving ASP files properly. Please tell me what is the reason behind all this. I have tried all versions after version 4.0. Why php version 4.xx is not working properly with IIS. I am surprised to know that no one has reported this problem and the creators have not fixed this problem yet.
