Section II Resource details
Understanding virtual computer name resources
Note 1 Create a virtual computer name control process per virtual computer name resource to
be activated. Make sure not to stop the process by mistake. An error of process
disappearance can be detected by virtual computer name monitoring resources.
Note 2 The following services are not available to the virtual computer name:
1. Mail slot
2. RPC (NetBIOS)
Note 3 Network printer connection cannot be set up from Control Panel. Use the net use
command for set up. The net use command displays information related to connecting
or disconnecting a computer to shared resources. The command controls network
connectivity in the next logon as well. For details on the net use command, refer to the
OS Help.
Note 4 When the virtual computer name and floating IP address are not linked, the following
needs to be considered:
• In the x64 environment, the configuration where the virtual computer name and the
floating IP address are not linked is not supported.
Do not forget to link them in the x64 environment.
• When using the virtual computer name from Windows 98 or Windows Me client, install
ExpressCluster Client and configure client settings.
• It may take a few minutes to reconnect to the cluster after failover due to a failure of the
server. This can be avoided by installing the ExpressCluster Client and configuring
client settings.
• It may take a few minutes to display the virtual computer name in the network computer
after the cluster is started.
• The virtual computer name cannot be written to LMHOSTS.
• When you have the settings to use a DNS server and the DNS server is associated with
WINS, switching by failover cannot be done while cache information of the virtual
computer name remaining on the DNS server. Configure the time to retain cache for
WINS to approximately 1 second on the DNS server.
Note 5 The NetBEUI protocol cannot be used if the virtual computer name and floating IP
address are linked.
Note 6 To register a virtual computer name with the WINS server on a remote network,
configure the following settings in cluster servers:
