Verify that the host name is correct and that your domain name server is working correctly.

When configured without the IBM® Configuration Assistant for z/OS® Communications Server, the host name setting is configured on the InitiateToLocation parameter of a LocalStartAction statement. See the information about the Policy Agent and policy applications in z/OS Communications Server: IP Configuration Reference for more information about the InitiateToLocation parameter.

When configured with the IBM Configuration Assistant for z/OS Communications Server, to verify that the host name setting is correct, edit the corresponding Connectivity Rule in the GUI. For Host to Gateway or Gateway to Gateway topologies, this setting is found on the Remote Security End Point panel. For Host to Host or Gateway to Host, this setting is found on the Advanced IPSec: Dynamic Tunnels: Local Activation panel. See the online helps in the GUI for additional information.
