Public network clients
cannot access the
applications or services
that are provided by the
cluster.
One or more nodes
may have the Internet
Connection Firewall
enabled, blocking
RPC communications
between the nodes.
Configure the Internet
Connection Firewall to allow
communications that are
required by the MSCS and the
clustered applications
or services.
See Microsoft Knowledge Base

You are using a Dell
PowerVault MD3000 or
MD3000i storage array
and Virtual Disks fail
over continuously
between the two storage
controllers when a
storage path fails.
The failback mode for
the cluster node(s) is
not set properly.
Set the correct failback mode on
each cluster node:
• For PowerVault™ MD3000,
you must merge the
PowerVault MD3000 Stand
Alone to
Cluster.reg file
located in the
\utility
directory of the Dell
PowerVault MD3000 Resource
Media into the registry of each
node.
• For PowerVault™ MD3000i,
you must merge the
PowerVault MD3000i Stand
Alone to
Cluster.reg file
located in the
windows\utility
directory of the Dell
PowerVault MD3000i resource
media into the registry of each
node.
You are using a Dell
PowerVault MD3000 or
MD3000i storage array
and Virtual Disk Copy
operation fails.
The Virtual Disk Copy
operation uses the
cluster disk as the
source disk.
To perform a Virtual Disk Copy
operation on the cluster share
disk, create a snapshot of the
disk, and then perform a Virtual
Disk Copy of the snapshot
virtual disk.
