If you change network settings on a node in a functioning cluster,
restarting the node may produce:
Event ID: 7023 Source: Service Control Manager Description: The Cluster Server service terminated with the following error: The endpoint cannot be created.If you manually start the Cluster service, you receive:
Could not start the Cluster Server service on <MachineName> Error 1720 The endpoint cannot be created.RPC is unabled to bind to the CDP ( Cluster Datagram Protocol), which is used for the heartbeat interface for inter-node communication.
To fix the problem, use Regedt32 to verify that permissions on the following keys are proper and the Provider List value name is correct:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Winsock\Setup Migration\Providers\Clusnet
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Winsock\Setup Migration
Value Name: Provider List
Data Type: REG_MULTI_SZ
Data: Clusnet (There will be other data values as well)
Verify permissions and that the Transports value name is correct:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Winsock\Parameters
Value Name: Transports
Data Type: REG_MULTI_SZ
Data: Clusnet (There will be other data values as well)
NOTE: If everything is correct, you may need to reinstall the Cluster service on the node.
NOTE: If Cluster Logging is enabled, the log may contain:
\[CS\] Initializing RPC server. \[INIT\] Unable to bind RPC to CDP, status 1720 \[CS\] ClusterInitialize failed 1720 \[INIT\] The cluster service is shutting down. \[FM\] Shutdown: Failover Manager requested to shutdown groups. \[FM\] FmpCleanupGroups: Entry \[Dm\] DmShutdown \[DM\] DmpShutdownFlusher: Entry \[DM\] DmpShutdownFlusher: Setting event \[DM\] DmpRegistryFlusher: got 0 \[DM\] DmpRegistryFlusher: exiting \[CPROXY\] clussvc terminated, error 1720 \[CPROXY\] Service Stopping... \[CPROXY\] Cleaning up \[CPROXY\] Cleanup complete. \[CPROXY\] Service Stopped.
