One of the nodes takes a long time to join the cluster.

The node-to-node network has failed due to a cabling or hardware failure.

Check the network cabling. Ensure that the node-to-node interconnection and the public local area network (LAN) are con- nected to the correct network interface controllers (NICs).

Long delays in node-to-node communications may be normal.

Verify that the nodes can communicate with each other by running the ping com- mand from each node to the other node. Try both the host name and Internet Pro- tocol (IP) address when using the ping command.

Clients are dropping off of the network while the cluster is failing over.

The service provided by the recovery group becomes temporarily unavailable to cli- ents during fail-over. Clients may lose their connection if their attempts to reconnect to the cluster are too infre- quent or if they end too abruptly.

Reconfigure the dropped client to make longer and more frequent attempts to reconnect to the cluster.

The Snmp.exe - Entry Point Not Found dialogue box appears during system start-up.

The Windows NT system errantly reports this condi- tion if the Simple Network Management Protocol (SNMP) service was installed after Windows NT and the Service Pack was installed.

Reapply the Windows NT Service Pack and any necessary hotfixes and drivers. See “Installing the Windows NT Service Pack and SCSI Hotfix” found in Chapter 1 for more information.
