    Are you sure CNO ( cluster name object ) has enough permissions into DNS? Were you successfully able to create listener with less than 15 characters?

    Hi,

    No I was not able to create.
    Just to clarify, Listener name I tried was less than 10 characters only. It's windows cluster name that was created with more than 15 characters.

    Later I recreated windows cluster with another short name and everything worked fine , including listener creation.

    Thanks.
