Search Engine Friendly URL's

Hi, Recently read an article about search engine friendly urls. (http://www.zend.com/zend/spotlight/searchengine.php?days=10000&f_id=searche ngine&mode=&kind=sl&article=searchengine) Seems good but for the life of me I cant get it to work on my IIS server. I've tried all the suggestions in the comments section of the above article to no avail. I've run PHP as both CGI and ISAPI, and I've run the MS knowledge base fix. Can anybody help with how to get $PATH_INFO from '...index.php/value1/value2/value3' using WK2 server and IIS. It works fine on the hosted Apache/*nix box but not on intranet w2k/IIS All I keep getting is : Warning: Unknown(D:\public_html\fun): failed to create stream: No such file or directory in Unknown on line 0 Warning: Unknown(): Failed opening 'D:\public_html\fun' for inclusion (include_path='.;d:\includes') in Unknown on line 0
