Whether you select to create a node from the Workgroup server’s pop-up menu or by clicking the Add button 
within a nodes viewlet, the Node Properties window opens.
Specify all properties of the new node. Enable the Use DNS option to automatically populate the IP Address field when the Host Name is specified.
Please note that the default Node Type is M6-WMQ Agent-managed MQ Node. Switch the Node Type to EMS Agent-managed Node to create an EMS node instead.
Click Ok to create the node.
