SYMPTOMS
In Windows Powered NAS 2.01, when you use either the shutdown functionality or the restart functionality in the Web UI, the system does not shut down.

The problem does not occur when you log on locally, or when you log on by using Terminal Services.



CAUSE
This problem is caused by an interaction between Windows Powered NAS and the Remote Procedure Call process (Rpcss.dll).

MORE INFORMATION
Only the following two Windows APIs can shut down or restart a computer:
 * ExitWindowsEx: This API requires an interactive user.
 * InitiateSystemShutdownEx This API works with built-in accounts, but requires that the user physically turn off the computer.

Windows 2000 did not always enforce the interactive user requirement of the ExitWindowsEx API. Security update 824141 (MS03-045) corrects a buffer overrun in the ListBox and the ComboBox controls and also causes the ExitWindowsEx API to enforce the interactive user requirement. Enforcing the interactive user requirement causes inconsistencies in scheduled, immediate, and software update restarts. Hotfix 835965 corrects this inconsistency by changing to the InitiateSystemShutdownEx API. However, the API change alters the shutdown behavior of the Windows Powered NAS server and now prevents the user from using the WebUI to schedule a remote shutdown or restart. To turn off the server remotely, the user must now use a Terminal Services session to shut down the server.
