Assembly: System.EnterpriseServices (in system.enterpriseservices.dll)
As messages arrive on the Xact Dead Letter queue, COM+ attempts to invoke a server-side exception handler related to the server class to deliver this notification. It does so by first calling FinalServerRetry, then calling the exception handling version of the failed method in the exception handler object. This exception method can then take an exception action, such as recording the failure, sending a mail message to the administrator, or taking client-side compensating action (reversing the effect of an earlier transaction). The server object should make every effort to complete this transaction successfully. Otherwise, manual intervention is required to reprocess the message. If the exception method is not successful, the message is moved to the final resting queue.
