is_dir() question regarding windows authentication

Happy New Year all! I have a PHP script (or a set of them really) that I have developed since the summer. One of the script will read a database and display to the user the contents of the directory. the directory by the way is store absolute full pathname. I even worked out the REGEX routine to convert the DOS file pattern to only show those files that match. Just so you know this all works. Here is my problem. I am currently running this under W2K Server, IIS PHP 4.3.0RC2 CGI version. I am using NT or IIS Authentication and the script works. I start converting my authentication process to simply present the use with a login HTML form and once posted the user is authenticated against a database. I sure this has something to do with IIS not allowing the directory access or something. Basically the call to 'is_dir($pathName)' where $pathName is something like 'd:\\ftproot\\FTPAccounts\\'. is_dir() returns FALSE. Any ideas how to get arround this? __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable. Sign up now. http://mailplus.yahoo.com
