When i try
bin\elasticsearch --enrollment-token MyErrollMent
It show an error
ERROR: Skipping security auto configuration because it appears that the node is not starting up for the first time. The node might already be part of a cluster and this auto setup utility is designed to configure Security for new clusters only.
I have seen a few posts about this error and i try :
- run bin/elasticsearch-reconfigure-node
 - start elasticsearch service
 - run bin\elasticsearch-create-enrollment-token -s node
 - run bin\elasticsearch --enrollment-token 
and I still get this error. 
My cluster heal is green.
