WLBS Cluster Servers Show Multiple Default Hosts

• Microsoft Windows NT Server version 4.0
• Microsoft Windows NT Server, Enterprise Edition
• Windows NT Load Balancing Service

SYMPTOMS

After you start the cluster hosts, the hosts report that convergence has completed, but more than one host is a default.

CAUSE

Probably causes are as follows:

1. The cluster hosts have become subnetted so that all hosts are not reachable on the same network.



2. Different network addresses are being used across the cluster, and the cluster's primary IP address was not entered into the TCP/IP configuration for the Windows NT Load Balancing Service (WLBS) Virtual NIC.



3. Different clusters are running on the same subnet.

RESOLUTION

To resolve these issues, use the corresponding resolutions below:

1. Be sure that all cluster hosts can communicate with each other.



2. In the case of different network addresses being used, TCP/IP will not detect an address conflict, and multiple clusters will exist. Be sure to use one cluster primary IP address and a corresponding network address on all hosts within the same cluster, and be sure to enter the primary IP address in the TCP/IP configuration for the WLBS Virtual NIC.



3. If you use different primary IP addresses, each with unique corresponding network addresses, on various cluster hosts, you can create multiple clusters on the same subnet. This is a not a problem unless this behavior was not intended.
