SYMPTOMS
When you configure to drain a cluster node in a specified time on a computer that is running Microsoft Windows Server 2003, the node remains in drain mode after the specified time has elapsed. For example, when you configure to drain a cluster node in one minute, you expect the node to be offline after one minute. However, the node remains in drain mode. You experience this problem when the following conditions are true:
 * You are running Microsoft Application Center 2000.
 * You configure the Application Center 2000 cluster to use Network Load Balancing (NLB).

Additionally, when you experience this problem, the following event messages are logged in the event log:

Message 1

Event Source: WLBS

Event ID: 44

Time:

Description: NLB Cluster  : Connection draining started.

Message 2

Event Source: WLBS

Event ID: 28

Time:

Description: NLB Cluster : Host 32 converged with host(s) 31,32 as part of the cluster.

Message 3

Event Source: WLBS

Event ID: 6

Time:  AM

Description: NLB Cluster  : Cluster mode stopped.

Note You do not experience this problem in Application Center 2000 clusters that are running on Microsoft Windows 2000 Server.

<div class="cause_section">

CAUSE
This problem occurs because Windows Server 2003 NLB event sequences have changed. This change may cause the Application Center engine state to be undetermined.
