The load-balancing status may not be set correctly in Application Center 2000 when you drain a node from load-balancing (898084)

SYMPTOMS

When you drain a node from load balancing, the load-balancing status may not be set correctly in Microsoft Application Center 2000. This problem occurs in the Application Center snap-in and when you use the Application Center 2000 command-line tool (Ac.exe) to monitor the status.

For example, when you run the AC LOADBALANCE /STATUS command, the load-balancing status that is returned is Online when you expect the status to be Offline.

Note This problem only occurs in Microsoft Windows Server 2003.

CAUSE

This problem occurs because of a bug in the Windows Management Instrumentation (WMI) Event Log provider. The WMI Event Log provider may take longer than expected to notify WMI subscribers of events. Because Application Center 2000 subscribes to WMI for load-balancing events, this delay may cause Application Center 2000 to return the incorrect load-balancing status.

RESOLUTION

To resolve this problem, install the hotfix that is described in the following Microsoft Knowledge Base article:

833010 The WMI Event Log provider takes a long time to notify the WMI subscriber when multiple event logs are written to an event log file
