I'm trying to create a form to allow uploading of files to the windows 2003 server which houses the HTML page.

I have PHP5 installed and am using a PHP script that the HTML file references. The error I'm getting when testing the upload is

HTTP Error 401.3 - Unauthorized: Access is denied due to an ACL set on the requested resource.
Internet Information Services (IIS)

I 'm listing the HTML code and the php code as well

HTML
<form enctype="multipart/form-data" action="file-upload.php" method="POST">
  <div><?php echo $message; ?></div><?php echo $max_file_size_tag; ?>
 
Please select file to upload: <input type="file" size="20" name="filename">
  <input type="submit" value="Upload" name="submit">
 
PHP
<?php

Make sure that all your PHP scripts have Execute permissions. If you are not sure which user to grant the permissions to, then give "Everyone" these permissions to confirm that this solves your problem.

There are two subfolders inside the PHP folder that will also need special permissions.

c:\php\sessiontemp
c:\php\uploadtemp

Make sure both of these files are readable and writable by the IUSR.

I am still fairly convinced that this is a permissions problem. Just to rule out the possibility that the wrong user is being given these permissions, can you temporarily give Everyone "full control" on the files and folders we've tried up to this point. Make sure to allow folder permissions to overwrite the permissions of their children. See if that changes anything.

hmm more and more I'm thinking that php5 may not be fully configured correctly... although I've gone through the settings in IIS and the php.ini and everything should be in order there.
I enabled register_globals just to see and after trying to upload I got a pop up error on the server saying..well I uploaded the screenshot of the error.
also after doing that the upload never seemed to finish but it never errored. Also BTW the file I'm trying to upload as a test is only 22kb

I resolved the issue by un-installing PHP and re-installing it. I had parts of an older version still on the server. Thanks... I'll award half the points for your help
