The following symptoms occur at the end time of a daylight saving period in Microsoft BizTalk Server 2004.

If an orchestration has a delay shape that causes the orchestration to end after the end time, the orchestration skips the shape and is completed. However, if the orchestration finishes before the end time, the orchestration proceeds as expected.

If an orchestration has a long-running transaction, and the time-out delay lands beyond the end time, the transaction times out as soon as it is started. If the transaction lands before the end time, the transaction proceeds as expected.

If an orchestration has an atomic transaction with retries enabled, and the transaction is being retried at the end time, the orchestration will be suspended. If this hotfix is not applied and this issue occurs, the orchestration is suspended and can be resumed manually. To manually resume service instances in BizTalk Server 2004, follow the steps in the "Workaround" section.
