The Performance tool in Windows Server 2003 displays an incorrect value for the "Avg Recipients/msg Sent" counter when you send an SMTP message to an Exchange Server 2003 recipient

Consider the following scenario:

• You configure the Performance tool to display values for the Avg Recipients/msg Sent counter for the SMTP Server performance object.
• You send an SMTP message to an e-mail recipient.
• This message is sent between two computers that are running Microsoft Exchange Server 2003.

In this scenario, when you view the value for the Avg Recipients/msg Sent counter, you notice that the value is incremented by 2. You expect the value to be incremented by only 1 because you sent the message to only one recipient.

This problem occurs if you are running Exchange 2003 on a computer that is running Microsoft Windows Server 2003.

Note This problem does not occur if you are running Exchange 2003 on a computer that is running Microsoft Windows 2000 Server Service Pack 3 (SP3) or Microsoft Windows 2000 Server Service Pack 4 (SP4).
