Updates that are made to alerts in the destination management group may not be applied in the zone management group in Microsoft Operations Manager 2005 (892096)

RESOLUTION

A hotfix is available that lets a MOM 2005 administrator modify the MOM 2005 configuration so that the destination management group update takes precedence when an alert update conflict occurs.

After you apply this hotfix and set a registry key on all source Management Servers, the default behavior is reversed. When an alert update conflict occurs, a change in the destination management group takes precedence over a change in the source management group. However, changes in the source management group are not applied in the destination management group when a conflict occurs.
