Why my cluster Failover eveyday

I have my cluster CCR with windows 2008 and Exchange 2007 SP1 , I'm facing a
problem that the cluster failover almost everyday and I didn't found any
error only 1135 but I didn't find any information that tell me why the
cluster was switched between Nodes.

The validation Wizard doesn't show any error

Any Idea or away to find more information about this issue

Thank You

Event ID 1135 description is this:

Cluster node <node name> was removed from the active failover cluster
membership. The Cluster service on this node may have stopped. This could
also be due to the node having lost communication with other active nodes in
the failover cluster. 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 adapters on this node. Also check for
failures in any other network components to which the node is connected such
as hubs, switches, or bridges.

Usually this is caused by some sort of connectivity problem between the
nodes.
are there any other events which are leading up to this ?

Hi Abdessadek,

you should check your cluster logs during the eventlog period which need to
created via cluster /log gen.
