ping-node-dcom
Tests if a node that is enabled for communication over DCOM is usable.
Description
The ping-node-dcom subcommand tests if a node that is enabled for communication over the Distributed Component Object Model (DCOM) remote
protocol is usable. The DCOM protocol is available only on Windows systems. This subcommand requires DCOM to be configured on the machine
where the domain administration server (DAS) is running and on the machine where the node resides. You may run this command from any
machine that can contact the DAS.
If the node is usable, the subcommand displays a confirmation that the subcommand could connect to the node through DCOM. This confirmation includes the name of the host that the node represents.
Optionally, the subcommand can also validate the node to determine if the asadmin utility can run on the
host that the node represents. To validate a node, the subcommand runs the version subcommand. If the node is
valid, the subcommand displays the version that the version subcommand returns.
The node that is specified as the operand of this subcommand must be enabled for communication over DCOM. If the node is not enabled for
communication over DCOM, an error occurs. To determine whether a node is enabled for communication over DCOM, use the
list-nodes subcommand.
To test whether a node that is enabled for communication over secure
shell (SSH) is usable, use the ping-node-ssh subcommand.

This subcommand is supported in remote mode only.

Examples
Example 1 Testing if a DCOM-Enabled Node Is Usable
This example tests if the DCOM-enabled node wpmd2 is usable.
asadmin> ping-node-dcom wpmdl2
Successfully made DCOM connection to node wpmdl2 (wpmdl2.example.com)
Command ping-node-dcom executed successfully.Example 2 Validating a DCOM-Enabled Node
This example validates the DCOM-enabled node adc-node.
asadmin> ping-node-dcom --validate=true adc-node
Successfully made DCOM connection to node adc-node (adc-node.example.com)
