ID: Q216333

The information in this article applies to:

Microsoft Windows NT Server, Enterprise Edition version 4.0

Windows NT Load Balancing Service

SYMPTOMS

The following Windows NT Load Balancing Service (WLBS) Event 18 appears in Event Viewer:

Duplicate cluster subnets detected. The network may have been inadvertently partitioned.

WLBS Cluster appears to function normally.

CAUSE

This event is generated on the remerging of a cluster that has been split into more than one cluster. This event can be caused by:

Pulling the net tap on a server, which will cause the server to converge with itself and two clusters will form.

Severing a trunk between two switches if the cluster is deployed across them.

RESOLUTION

This event is an informational message that reports the network had been partitioned and the WLBS hosts now have correctly converged in just one cluster.

STATUS

This behavior is by design.
