| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | 0 |
Places timed-out or undeliverable messages in the XactDeadLetter queue.
In MSMQ 1.0, timed-out or undeliverable transactional messages were placed in the XactDeadLetter queue by default. In Windows 2000, the messages are placed in the XactDeadLetter queue only if the MSMQ_DEADLETTER property is selected.
Setting the value of this entry to 1 forces the local Message Queuing service to revert to MSMQ 1.0 behavior. Use this entry when the change in default behavior might break the existing application.
| Value | Meaning |
|---|---|
| 0 | Messages are placed in the XactDead Letter queue only if the message property (MSMQ_DEADLETTER) was set on the message. |
| 1 | Messages are placed in the XactDeadLetter queue. |
Note
Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
