SYMPTOMS
The cluster resource manager may not detect that a server in your cluster is unavailable.

When you view the server cluster log file (Cluster.log) you may notice information that is similar to the following information. This information indicates that the IsAlive polling determined that the cluster node was still responding:

00002f0.00000f38::2002/07/09-17:03:44.564 Microsoft Exchange Information Store : [EXRES] calling EcStoreIsServerAlive

00000740.00001408::2002/07/09-17:03:44.627 [EVT] s_ApiEvPropEvents: Calling into EvpPropPendingEvents, size=776...

00000740.00001408::2002/07/09-17:03:44.627 [EVT] s_ApiEvPropEvents: Called EvpPropPendingEvents...

Additionally, you may notice the following information in the server cluster log file:

000002f0.00000f38::2002/07/09-17:03:45.143 Microsoft Exchange Information Store : [EXRES] EcStoreIsServerAlive returned error 0, fIsAlive=TRUE
