follow the steps:
- stop all aplications in cluster (With Cluster Administrator).
- stop cluster service and change startup to manual.
- change domain machine/reboot server(s).
- create a account to cluster service in new domain.
- add account to administrator group (local group) on all nodes cluster, or add permisions to account, required do run properlly cluster service. I don't remember now how permissions much you can find at microsoft.com, remenber create a account with another name because if you use a same name a SID account is different of a original account/domain
- change service account who startup the cluster in all nodes via services.msc snap in.
- on primary node change service to automatic start up, restart node.
- verify cluster service if it start on primary node.
- if Ok , repeat steps (change service account) on all nodes of cluster.
Some problems mail me.
