Lost Cluster service account password here how to reset it without downtime




Yes you heard right. I am trying to bring another node into existing cluster and I am at the point where I need to supply the Cluster service account password, I am not able to figured out what the password was set too. Of course the person who set the cluster Exchange did not save or document the password for job security reasons and he is no longer at this place. I desperately go over the entire existing password save programs for this company and the result no luck. This Cluster environment is pretty large and there is no room for mistake, so being cautious we ended up calling PS support for Microsoft.

cluster /cluster:nhqCluster /changepassword /skipdc

My cluster name is nhqCluster so; replace this with your cluster name. This command line works like a charm and replaces the password with the new password you will be supplying beside this method I have also figured out, following way works as well. Stop Cluster services on all nodes, go to services make sure cluster service is stopped. Go to properties and reset the password on all the nodes, go back and restart the services. This is involving stopping the cluster; the command line won't cause any interruption on the cluster

Steps:

  • First we will change/reset the password for cluster service account in the Active directory.
  • On every cluster node, click Start, click Run, type services.msc, and then click OK.
  • In the Services (Local) list, double-click Cluster Service.
  • Click the Log On tab and then type the Cluster service account in the account box by using the Universal Naming Convention (UNC) format. For example, type an account name that is similar to the following: SMTp25\ clusteraccount
  • Type the correct account password in the Password box and in the Confirm password box, and then click OK.


  • When you receive the following message, click OK: The new logon name will not take effect until you stop and restart the service.
  • Under Cluster Service, click the Restart link.
  • Then follow the article KB305813
  • If it doesn't work the we need to follow the article KB269229 How to manually re-create the Cluster service account

When you change the password successfully on the cluster nodes if you are still not able to add the node, probably node is reading the password for the service account from DC, remember in the command lien we had switch Skipdc “cluster /cluster:nhqCluster /changepassword /skipdc”
So go to your DC and reset the account password same as the password you set for the nodes
Charm work we are in business
