Virtual Directory Problem

I want to create a virtual directory on a web site running on IIS5 and PHP 3.0.16. The website itself is running fine, the virtual directory should basically pont to same folder as the web root, its purpose is to enable me to switch databases depending on the folder the user is pointing at. e.g. mydomain.com\index.html will use database A mydomain.com/new/index.html will use database B (or other, specific tables from database A) The problem is that all files in the virtual directory parsed by PHP give me the notorious "No input file specified" error. So, looks like php.exe can't find them, because it's trying to find the virtual directory "new" in the file structure of the webroot directory. Non-php files display correctly. Has anybody experienced this problem? Any workarounds? Basically, I need to be able to acces the same set of files from two different locations and o be able to make some switches depending on the file path in $PHP_SELF Andrian
