SYMPTOMS
Microsoft Windows Server 2003 may stop responding when you enable the Sender ID Filtering setting on a Simple Mail Transfer Protocol (SMTP) virtual server in Microsoft Exchange Server 2003 Service Pack 2 (SP2).

Note You can enable the Sender ID Filtering setting in the Global Settings folder in Exchange System Manager on the individual SMTP virtual server.



CAUSE
This problem occurs because of a race condition that is caused by the SMTP protocol.

Note A race condition occurs when a device or a system tries to perform two or more operations at the same time. Because of the nature of the device or system, the operations must be performed in the correct sequence in order to be completed correctly.
