Cluster Failing

Hi

I have a 6 node cluster setup on win 2003 machines
I am in the process of testing failover on the systems.
If I stop the clusterservice on the node which is holding the Quorum resousource, fail over happens as expected.If I hard power cycle the server with the resouce all the cluster services on the rest of the nodes stop and the following event in the event log are logged on each server

Event Category: Physical Disk Resource
Event ID: 1034
Event Category: Startup/Shutdown
Event ID: 1073
Event Category: Membership Mgr
Event ID: 1177
Event Category: None
Event ID: 1209

The cluster services will not start until the machine is back up and it see's the quorum again

Any help would be appreciated

Thanks
