Before you can enable NT domain authentication on any specific cluster, you must create an NT user group with a name in the form: "BT_clustername" within the domain you want to secure.
You or the domain administrator can do this through the standard Windows NT User Manager for Domains utility. Once you create a "BT_clustername" group, any of the users you add to that group are authenticated to view the cluster. All members of the cluster must be from the same Windows NT domain unless a trusted relationship has been set up between two or more domains by the system administrator.
A "BT_clustername" global group must exist in the domain from which the ClusterCATS Explorer is executed. Cluster members in other domains need only the trust relationship. ClusterCATS Explorer determines what servers exist in which NT domain by communicating with any Windows NT domain controller for the domain. The list of servers that exist in the Windows NT domain can be viewed by looking at the Network Neighborhood Windows NT utility. If no trust relationship exists, then cluster members must be from the same Windows NT domain.
