Problem
How to install and configure the Microsoft NLB provider on a Windows NT 4.0 WLBS Cluster.
Solution
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.
Resolution
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.
Prerequisites
- 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.
Provider Installation
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.
Perform the following steps:
1. Copy
msvcp50.dll to c:\winnt\system32
2. Copy
wlbsctrl.dll to c:\winnt\system32
3. Copy
wlbsprov.dll to c:\winnt\system32\wbem
4. Copy
wlbsprov.mfl to c:\winnt\system32\wbem
5. Copy
wlbsprov.mof to c:\winnt\system32\wbem
6. Execute
regsvr32 wlbsprov.dll
7. Execute
mofcomp -AUTORECOVER c:\winnt\system32\wbem\wlbsprov.mof
8. Execute
mofcomp -AUTORECOVER c:\winnt\system32\wbem\wlbsprov.mfl
Using the WMI Object Browser that is installed with the
WMI SDK, the "root\MicrosoftNLB" object path should be visible under the machine
running the provider.
Thank you.
