Message content does not expire correctly, message content remains on the NTFS file system, and a memory leak occurs in Windows Server 2003 (831186)

SYMPTOMS

In Microsoft Windows Server 2003, you may experience one or more of the following problems with the Network News Transfer Protocol (NNTP) service:

The content of a message is not removed from the NTFS file system if that message is rejected by a program such as an antivirus program.

In Windows Server 2003, an event sink interface is available that lets programs interact with the NTFS file system. A program can use this event sink to reject a message by resetting a flag.

However, when the onpost event is triggered, the content from the message that triggered this event is already stored in the NTFS file system. If the event sink rejects this message, only the hash table entry for that message is actually removed. The message content remains in the NTFS file system.
Message expiration does not work correctly after you rebuild an NNTP virtual server.

After you rebuild an NNTP virtual server, NNTP messages that are configured to expire after a certain time do not expire correctly. The message item time in the hash table is stamped with the current NNTP virtual server rebuild time.
A memory leak occurs when you configure multiple sink events for the NNTP service.
