IIS 6 - 404 all the time

Hi, I just tryed to install php-4.3.2-Win32 on a Windows 2003 Server with IIS 6. I copy all files to C:\PHP Copy php.ini-dist to C:\WINDOWS and renamed it to php.ini Enabled by unmark and changed "cgi.force_redirect = 0" Changed extensions_dir = "C:\PHP\extensions" Gave IUSER_<machinename> (surf account) rights to read and execute in C:\PHP Copy .DLLs to C:\WINDOWS\SYSTEM32 In IIS6 Manager I added under my defaltsite the PHP.EXE and mapped it to ..PHP, PHP3 If I put any html-file in the defaultsite I got it via browser but if I tries to execute any .PHP I got 404. I tried to unmark "Verify that file exists" and the 404 is unchanged Any idéas? Best Regards Johan Ryberg
