I'm trying to use the permission checker component with IIS4.0, but only receive an access denied message. The component is being used on a company intranet web site to determine access levels for files located on a network PC. I've set the root web directory authentication methods to "Windows NT Challenge/Response" only. Are there any other settings to adjust within IIS4.0 or for the network directory containing the files? To complicate matters, browser settings for company users s are set to use a proxy server. If there is an easier approach to checking file permission on a network PC, please let me know. Thanks.
