Apple Mac OS X Server (version 10.2.3 or later) - Manual (Page 333)

Client Management: Mac OS X 333
Users See a Message About an Unexpected Error
When you manage Classic preferences and try to use the Extensions Manager, File Sharing,
and Software Update control panels, you may see a message that says “The operation could
not be completed. An unexpected error occurred (error code 1016).” This message indicates
that an administrator has restricted access to the item the user attempted to use.
Users are not allowed to access the control panels mentioned above when Classic
preferences are managed. Users may also see the message if you have selected “Hide
Chooser and Network Browser” and you attempt to use the Chooser.
The message also appears when a user tries to open an unapproved application (one that is
not listed in the Items pane of the Applications preference in Workgroup manager) in either
Classic or Mac OS X.
