The Active Directory server is offline. Authentication services might be interrupted.

The node cannot contact an authentication server for the specified domain. By design, the node periodically attempts to re-establish communication with the domain. If the node successfully connects to the domain, the event clears itself.

Administrator action

Confirm that TCP port 389 is open on your network.

If the event does not clear itself within five minutes or if the event recurs, perform the following steps on the node on which the issue occurred:

  1. Ping the authentication server.
    • If the ping operation fails, confirm that network connectivity exists between the cluster and the authentication server.
      • If you can establish contact between the cluster and the authentication server, attempt to ping the authentication server again to see if the issue has resolved.
      • If you cannot establish contact between the cluster and the authentication server, attempt to resolve any network connectivity issues.
    • If the ping operation succeeds, verify that your authentication server is online and functional.

If the event persists, gather logs, and then contact EMC Isilon Technical Support for additional troubleshooting. For instructions, see Gathering cluster logs.
