SYMPTOMS
You may experience the following symptoms on a computer that is running Microsoft Exchange Server 2003:   The IIS Admin Service (Inetinfo.exe) crashes. In this situation, the following event is logged in the System log: Event Type: Error

Time:

User: N/A

Computer:

Description: The IIS Admin Service service terminated unexpectedly. It has done this 2 time(s). The following corrective action will be taken in 1 milliseconds: Run the configured recovery program.  Mail builds up in the SMTP queue.

If you turn off the message tracking component in Exchange, you no longer experience this problem.

Note You may experience this problem more frequently on a heavily loaded Exchange gateway server.



CAUSE
This problem occurs because of a problem in the message tracking component in Exchange. The message tracking component may crash when it tries to obtain the properties of a Mailmsg object. This problem occurs because a thread that queues a message for remote delivery runs at the same time as the message tracking thread that logs the event that states that the message is queued for remote delivery. This problem occurs in the following situation:
 * Exchange queues a message for remote delivery.
 * The message tracking thread starts to log an event that states that the message is queued for remote delivery.
 * The message is delivered and then removed by a different thread.
 * The message tracking thread tries to obtain the properties of the Mailmsg object that was removed to finish the logging operation.

In this situation, the message tracking component crashes when it tries to obtain the properties of the Mailmsg object because the Mailmsg object has been removed.
