Mismatch between the registry entries on the server and the workstation.


  1. Check for the following registry key on the server and the workstation:
    HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.5\Enterprise\CMSClusterMembers.
  2. CMSClusterMembers entries should be same as that on the server and the workstation. For example: if the workstation has IP address of the server in the CMSClusterMembers and the server has hostname of the server, then modify the CMSClusterMembers on the workstation.
