  • Update the NetWorker client and server to the latest release.
  • Rebooted each physical node in the cluster.
  • Verify that NetWorker aliasing for the physical and virtual clients is correct.
  • Verify that name resolution for physical and virtual clients is correct.
  • Remove and re-add the base enabler to the NetWorker Server.
  • Multiple client resources are configured for the same physical clients.
  • Verify that cluster client did not take physical license.
