SYMPTOMS
After an Application Center 2000 (AC2000) cluster creation or a member addition in a cluster with multiple virtual IP addresses (VIPs), some static IP addresses may not be assigned. If a cluster member is removed, the VIPs may not be removed from the cluster member. If a script or program uses Windows Management Instrumentation (WMI) to remove or add static IP addresses on the cluster controller, the addition or removal may not be correctly replicated to the cluster members. In all cases, the address assignment may appear to be correct in the Network Connections user interface, but IPConfig reports the actual address settings and the cluster may not function correctly.



CAUSE
This problem may occur when the WMI EnableStatic method of the Win32_NetworkAdapterConfiguration class does not add or remove a static IP address without reporting a failure.



RESOLUTION
To resolve this problem, disable and reenable the network interface card, and then retry the cluster operation that was not successful.
