Nginx Windows URL Rewrite Error - php

Question

I installed a portable nginx and php5.3 on windows 7 64bit and I created a sample site needs a url rewrite to run this is the error I always get after my configuration.
2014/11/30 22:56:12 [crit] 2356#3384: *1 GetFileAttributesEx() "D:/nginx/nginx/nginx-1.2.3/html/main.site.dev/index.php/" failed (123: The filename, directory name, or volume label syntax is incorrect), client: 192.168.1.109, server: main.site.web, request: "GET / HTTP/1.1", host: "main.site.web"
here is my current windows nginx server block config:
server {
listen 80;
server_name main.site.web;
root D:/nginx/nginx/nginx-1.2.3/html/main.site.dev;
location / {
try_files $uri index.php$uri$args /index.php$uri$args /index.php;
}
location ~ \.php\/(.+)$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
break;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
}
location = /php-fpm-ping {
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
}
}
Notice the "/" at the end of "index.php". What is wrong with the configuration.
Also note that the directory on this window is fully controlled (read & write).
Any suggestion or comments are appreciated. Thank you in advance...
