A. File screens are a new technology in Windows Server 2003 R2, and as such, clients would not understand a file screen violation error, so they'll simply receive an Access Denied message, like the one that the figure shows.
This is why it's important that as part of file screen actions, you configure an email message to be sent to the offender, which will explain why the person got the Access Denied message. The email message could also contain a link to corporate file server usage policies. This step will avoid countless Help desk calls from users asking why they receive Access Denied messages.
