How to install and configure the Microsoft NLB provider on a Windows NT 4.0 WLBS Cluster.
The NLB provider is a Windows Management Instrumentation (WMI) component that ClusterX for NLB 1.1 needs to enable certain features. The NLB provider ships on all Windows 2000 (W2K) versions and therefore the features are available in an all-W2K environment. However, there is no WLBS provider available for Windows NT 4.0. In an environment with Windows NT 4.0 WLBS clusters, the following ClusterX for NLB features are not available for those clustered nodes.
Port rules cannot be displayed, added, or modified.
Cluster Consistency Report does not report inconsistencies.
To obtain the ClusterX for NLB features listed above for Windows NT 4.0 clusters, the NLB provider can be manually installed onto Windows NT 4.0 WLBS clustered nodes. The NLB provider files are available on any W2K Server installation. The ClusterX Engineering team has thoroughly tested and qualified the NLB provider running on Windows NT 4.0 WLBS clusters with ClusterX for NLB 1.1.
Service Pack 5 or greater. Upgrade if necessary.
WMI Core Build 1085.*
* If it has not already been done, install this from the ClusterX for NLB 1.1 CD. Execute wmint4.exe from the WMI directory of the installation CD and install to each Windows NT 4.0 server node as desired.
The source of the NLB Provider files can be any W2K Server machine's \winnt\system32 and \winnt\system32\wbem directories. Copy the files (indicated below) directly from the W2K server by mounting a share remotely, or copy to a floppy disk to use as the source.
