the problems are
1. The cluster has stopped working .In the cluster administrator the network name ,first
storage group/mailbox database,Exchange System attendant instance failed to start.
2. Exchange Mailbox is completely down.
I checked Microsoft Exchange Information store service and it was in stopped state.
I tried out the registry changes as suggested in technet but that did not work out.
The following errors have occured in event viewer after a restart
