Microsoft Operations Manager 2005 agent alerts are not processed when the Ignore Missing Heartbeats option is enabled

Assume that you have selected a computer under Agent-managed computers or under Agentless managed computers in the Microsoft Operations Manager (MOM) 2005 Administrator Console. If you turn on the Ignore Missing Heartbeats option, the MOM Management Server does not process any alerts that are received from the MOM agent. Additionally, the alerts are not added to the MOM OnePoint database.

When the Ignore Missing Heartbeats option is enabled, the MOM 2005 agent generates alerts as usual. However, when the Management Server receives the alert for processing, the alert is discarded.

When the Ignore Missing Heartbeats option is enabled, the MOM 2005 agent goes into maintenance mode. Any alerts that are generated by the MOM agent are not processed or added to the MOM OnePoint database.

When you install this hotfix, only alerts generated by the following event processing rules are ignored:

• MOM Agent heartbeat failure - idProcessrule = B2FC934C-BE4F-4871-AFB4-E46E6A63F8DC - RulePath = Rule Groups\Microsoft Operations Manager\Operations Manager 2005\Server\Event Rules
