The following symptoms occur only during the fall standard time change in Microsoft BizTalk Server 2004.

If an orchestration has a delay shape that causes the orchestration to end after the 2:00 A.M. standard time change, the orchestration skips the shape and is completed. However, if the orchestration finishes before 2:00 A.M., the orchestration proceeds as expected.

If an orchestration has a long-running transaction, and the time-out delay lands beyond the standard time change, the transaction times out as soon as it is started. If the transaction lands before 2:00 A.M., the transaction proceeds as expected.

If an orchestration has an atomic transaction with retries enabled, and the transaction is being retried during the standard time change, 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.
