To safely remove a node from a Windows 2003 Fail-Over Cluster, follow these steps:

  1. First, using Cluster Administrator, move all roles to the other nodes in the cluster.
    There should be no more roles, including the quorum running on the node.
  2. In Cluster Administrator, right-click the node and click Stop Cluster Service. (Skip this step if it is the last node of the cluster.)
  3. Still in Cluster Administrator, right-click the node and click Evict node. This will remove the node from the cluster.
  4. Optionally, you can now remove the Fail-Over cluster components from the server.
