Disabling and Removing WLBS

• Microsoft Windows NT Server, Enterprise Edition version 4.0
• Microsoft Windows NT Server version 4.0
• Windows NT Load Balancing Service

SUMMARY

Windows NT Load Balancing Service (WLBS) can be disabled for troubleshooting purposes or because a computer is not going to participate in cluster operations for an extended period of time. Follow these steps to disable WLBS:

NOTE: Cluster Adapter is the network interface card (NIC) used for cluster traffic; it is not the WLBS Virtual NIC adapter.

1. In Control Panal, double-click Network, and then click the Bindings tab.



2. Under Show Bindings For, select All Protocols.



3. Disable the binding from the WLBS driver protocol to the network adapter.



4. Disable the binding from the TCP/IP and WINS Client protocols to the WLBS Virtual NIC adapter.



5. If you are using multiple adapters and if you plan to use this adapter to handle TCP/IP and WINS Client traffic, enable the binding from the TCP/IP and WINS Client protocols to the cluster adapter.



6. Click OK to close the dialog box.



7. Restart the computer.

1. In Control Panal, double-click Network, and then click the Adapters tab.



2. Select the WLBS Virtual NIC Driver.



3. Click Remove.



4. Examine and modify (if needed) the bindings from the TCP/IP and WINS Client protocols to the cluster adapter as preferred.



5. Click OK to close the dialog box.



6. Remove the following files from the %SystemRoot%\System32 folder:
   
   
   • Wlbs.exe

   • Wlbs.hlp
