[TYPO3-windows] Virtual Directories and IIS

[Joel Finkel]

Folks,

I have all my websites on a network accessible server (NAS), called "NAS1". 
I set up a new virtual website in IIS called TYPO3, and set the virtual 
directory to "\\NAS1\Websites\TYPO3".

Unfortunately, line 49 of index.php contains this line, which converts "//" 
to "/" and "\\" to "\":

define('PATH_thisScript',str_replace('//','/', str_replace('\\','/', 
(php_sapi_name()=='cgi'||php_sapi_name()=='isapi' 
||php_sapi_name()=='cgi-fcgi')&&($_SERVER['ORIG_PATH_TRANSLATED']?$_SERVER['ORIG_PATH_TRANSLATED']:$_SERVER['PATH_TRANSLATED'])? 
($_SERVER['ORIG_PATH_TRANSLATED']?$_SERVER['ORIG_PATH_TRANSLATED']:$_SERVER['PATH_TRANSLATED']):($_SERVER['ORIG_SCRIPT_FILENAME']?$_SERVER['ORIG_SCRIPT_FILENAME']:$_SERVER['SCRIPT_FILENAME']))));

Therefore, "\\NAS1\Websites\TYPO3" becomes "\NAS1\Websites\TYPO3", and, 
because this is an invalid path, PHP cannot include any of the required 
files.

I would appreciate any suggestions as to how to properly deal with this 
configuration.  Obviously, I can change the index.php code, but I am rather 
loathe to modify such a fundamental file.

Thanks in advance,
Joel Finkel
