Hi,
I cna see you are using PHP5.2.14 Non Thread Safe and PHP is hosted on IIS using FastCGI. There should not be any problem.
You will need to be more explicit. See if PHP is logging anything is the log files. Can you tell me what application you are using which is giving you 500 all the time. Write a simple PHP program (other than phpinfo) and see if that works. You will need
to try few more things and isolate the problem. Because in general WINCACHE works just well on Wndows 2008 R2 x64 using IIS FastCGI and PHP 5.2.14.
Thanks,
Don.
