Hi ,
we have Active-Pasive-Active SCC exchnage 2007 Cluster running. daily in the 11 AM time we are getting below event error and after that cluster failing over to pasive node .
"The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the cluster, or a failover of the witness disk.
Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected
such as hubs, switches, or bridges."
we check all n/w component looks fine .
pl. help if any issue on cluster lavel .
thanks
