Resolution of problem:
Open php.ini file and review the doc_root setting.
Example of value could be following setting:
doc_root = "d:\Inetpub\wwwroot"
The comments above this setting say:
; The root of the PHP pages, used only if nonempty.
; if PHP was not compiled with FORCE_REDIRECT, you SHOULD set doc_root
; if you are running php as a CGI under any web server (other than IIS)
; see documentation for security issues. The alternate is to use the
; cgi.force_redirect configuration below
If you are using PHP in ISAPI mode, not CGI, try comment out the setting so it will look like this:
; doc_root = "d:\Inetpub\wwwroot"
Then save php.ini and restart IIS by opening a command prompt (Start => Programs => Accessories => Command Prompt) and type the command:
iisreset
This should fix the problem!
If it will not resolve problem, please ask your server administrator to resolve the problem - it is related to wrong configuration of PHP on your server
