PRB: Application Center 2000 Cluster Node Does Not Converge When Network Adapter Is Enabled on the Cluster Node (822987)


The information in this article applies to:

  • Microsoft Application Center 2000

SYMPTOMS

When you disable and then enable the public network adapter of an Application Center 2000 routing cluster node that is using Network Load Balancing, the cluster node may not automatically converge with the cluster.

WORKAROUND

To work around this problem, after you enable the public network adapter on an Application Center 2000 routing cluster node, run one of the following commands from the command prompt:
  • wlbs start
  • ac loadbalance /online
Note These commands permit the convergence of the cluster node to occur after the network adapter is enabled.

STATUS

This behavior is by design.

MORE INFORMATION

If you run Network Load Balancing without Application Center, you can select the Active check box in the NLB Configuration dialog box. This option permits the network card to automatically converge when the network card is enabled.

If you run Network Load Balancing with Application Center, you do not have the option to select the Active check box in the NLB Configuration dialog box. This option is not available because this option permits Application Center to keep Network Load Balancing offline while the computer starts until the W3SVC service starts. Otherwise, Network Load Balancing starts to serve the network load before Internet Information Services is ready to accept the load, and problems may occur.
