Trouble Removing WINS Addresses from Celerra

We are trying to static our WINS entries for the NAS servers.  Problem is that WINS is configured in the Celerra and it keeps adding entries back into WINS.  I've tried to run the following command: server_cifs server_x -delete wins=OldIP I get an error "Cifs del wins failed with error Unable to remove wins server" How can I remove WINS without disruption of access to file shares?
